There is evidence of continuous human habitation in present-day Thailand from 20,000 years ago to the present day.[25]^: 4 The earliest evidence of rice growing is dated at 2,000 BCE.[24]^: 4 Areas comprising what is now Thailand participated in the Maritime Jade Road, as ascertained by archeological research. The trading network existed for 3,000 years, between 2000 BCE to 1000 CE.[26][27][28][29] Bronze appeared c. 1,250–1,000 BCE.[24]^: 4 The site of Ban Chiang in northeast Thailand currently ranks as the earliest known centre of copper and bronze production in Southeast Asia.[30] Iron appeared around 500 BCE.[24]^: 5 The Kingdom of Funan was the first and most powerful Southeast Asian kingdom at the time (2nd century BCE).[25]^: 5 The Mon people established the principalities of Dvaravati and Kingdom of Hariphunchai in the 6th century. The Khmer people established the Khmer empire, centred in Angkor, in the 9th century.[25]^: 7 Tambralinga, a Malay state controlling trade through the Malacca Strait, rose in the 10th century.[25]^: 5 The Indochina peninsula was heavily influenced by the culture and religions of India from the time of the Kingdom of Funan to that of the Khmer Empire.[31]

The Thai people are of the Tai ethnic group, characterised by common linguistic roots.[32]^: 2 Chinese chronicles first mention the Tai peoples in the 6th century BCE. While there are many assumptions regarding the origin of Tai peoples, David K. Wyatt, a historian of Thailand, argued that their ancestors which at the present inhabit Laos, Thailand, Myanmar, India, and China came from the Điện Biên Phủ area between the 5th and the 8th century.[32]^: 6 Thai people began migrating into present-day Thailand gradually from the 6th to 11th century, which Mon and Khmer people occupied at the time.[33] Thus Thai culture was influenced by Indian, Mon, and Khmer cultures.[34]

According to French historian George Cœdès, "The Thai first enter history of Farther India in the eleventh century with the mention of Syam slaves or prisoners of war in Champa epigraphy", and "in the twelfth century, the bas-reliefs of Angkor Wat" where "a group of warriors" are described as Syam,[16]^{: 190–191, 194–195} though Cham accounts do not indicate the origins of Syam or what ethnic group they belonged to.[35] The origins and ethnicity of the Syam remain unclear, with some literature suggesting that Syam refers to the Shan people, the Bru people, or the Brau people.[35][36] However, mainland Southeast Asian sources from before the fourteenth century primarily used the word Syam as an ethnonym, referring to those who belonged to a separate cultural category different from the Khmer, Cham, Bagan, or Mon. This contrasts with the Chinese sources, where Xian was used as a toponym.[35]

After the decline of the Khmer Empire and Kingdom of Pagan in the early-13th century, various states thrived in their place. The domains of Tai people existed from the northeast of present-day India to the north of present-day Laos and to the Malay peninsula.[32]^: 38–9 During the 13th century, Tai people had already settled in the core land of Dvaravati and Lavo Kingdom to Nakhon Si Thammarat in the south. There are, however, no records detailing the arrival of the Tais.[32]^: 50–1

Around 1240, Pho Khun Bang Klang Hao, a local Tai ruler, rallied the people to rebel against the Khmer. He later crowned himself the first king of Sukhothai Kingdom in 1238.[32]^: 52–3 Mainstream Thai historians count Sukhothai as the first kingdom of Thai people. Sukhothai expanded furthest during the reign of Ram Khamhaeng (r. 1279–1298). However, it was mostly a network of local lords who swore fealty to Sukhothai, not directly controlled by it.[32]^: 55–6 He is believed have invented Thai script and Thai ceramics were an important export in his era. Sukhothai embraced Theravada Buddhism in the reign of Maha Thammaracha I (1347–1368).

To the north, Mangrai, who descended from a local ruler lineage of Ngoenyang, founded the kingdom of Lan Na in 1292, centered in Chiang Mai. He unified the surrounding area and his dynasty would rule the kingdom continuously for the next two centuries. He also created a network of states through political alliances to the east and north of the Mekong.[22]^: 8 While in the port in Lower Chao Phraya Basin, a federation around Phetchaburi, Suphan Buri, Lopburi, and the Ayutthaya area was created in the 11th century.[22]^: 8

Ayutthaya Kingdom

Ayutthaya and neighbours, c. 1540 CE.

According to the most widely accepted version of its origin, the Ayutthaya Kingdom rose from the earlier, nearby Lavo Kingdom and Suvarnabhumi with Uthong as its first king. Ayutthaya was a patchwork of self-governing principalities and tributary provinces owing allegiance to the King of Ayutthaya under the mandala system.[37]^: 355 Its initial expansion was through conquest and political marriage. Before the end of the 15th century, Ayutthaya invaded the Khmer Empire three times and sacked its capital Angkor.[38]^: 26 Ayutthaya then became a regional power in place of the Khmer. Constant interference of Sukhothai effectively made it a vassal state of Ayutthaya and it was finally incorporated into the kingdom. Borommatrailokkanat brought about bureaucratic reforms which lasted into the 20th century and created a system of social hierarchy called sakdina, where male commoners were conscripted as corvée labourers for six months a year.[39]^: 107 Ayutthaya was interested in the Malay peninsula, but failed to conquer the Malacca Sultanate which was supported by the Chinese Ming dynasty.[25]^: 11, 13

European contact and trade started in the early-16th century, with the envoy of Portuguese duke Afonso de Albuquerque in 1511. Portugal became an ally and ceded some soldiers to King Rama Thibodi II.[40] The Portuguese were followed in the 17th century by the French, Dutch, and English. Rivalry for supremacy over Chiang Mai and the Mon people pitted Ayutthaya against the Burmese Kingdom. Several wars with its ruling Taungoo dynasty starting in the 1540s in the reign of Tabinshwehti and Bayinnaung were ultimately ended with the capture of the capital in 1570.[39]^: 146–7 Then was a brief period of vassalage to Burma until Naresuan proclaimed independence in 1584.[22]^: 11

Ayutthaya then sought to improve relations with European powers for many successive reigns. The kingdom especially prospered during cosmopolitan Narai's reign (1656–1688) when some European travelers regarded Ayutthaya as an Asian great power, alongside China and India.[24]^: ix However, growing French influence later in his reign was met with nationalist sentiment and led eventually to the Siamese revolution of 1688.[39]^: 185–6 However, overall relations remained stable, with French missionaries still active in preaching Christianity.[39]^: 186

After a bloody period of dynastic struggle, Ayutthaya entered into what has been called the Siamese "golden age", a relatively peaceful episode in the second quarter of the 18th century when art, literature, and learning flourished. There were seldom foreign wars, apart from conflict with the Nguyễn lords for control of Cambodia starting around 1715. The last fifty years of the kingdom witnessed bloody succession crises, where there were purges of court officials and able generals for many consecutive reigns. In 1765, a combined 40,000-strong force of Burmese armies invaded it from the north and west.[41]^: 250 The Burmese under the new Alaungpaya dynasty quickly rose to become a new local power by 1759. After a 14-month siege, the capital city's walls fell and the city was burned in April 1767.[42]^: 218

Taksin the Great enthroned himself as a Thai king in 1767.

The capital and many of its territories lay in chaos after the war. The former capital was occupied by the Burmese garrison army and five local leaders declared themselves overlords, including the lords of Sakwangburi, Phitsanulok, Pimai, Chanthaburi, and Nakhon Si Thammarat. Chao Tak, a capable military leader, proceeded to make himself a lord by right of conquest, beginning with the legendary sack of Chanthaburi. Based at Chanthaburi, Chao Tak raised troops and resources, and sent a fleet up the Chao Phraya to take the fort of Thonburi. In the same year, Chao Tak was able to retake Ayutthaya from the Burmese only seven months after the fall of the city.[43]

Chao Tak then crowned himself as Taksin and proclaimed Thonburi as temporary capital in the same year. He also quickly subdued the other warlords. His forces engaged in wars with Burma, Laos, and Cambodia, which successfully drove the Burmese out of Lan Na in 1775,[39]^: 225 captured Vientiane in 1778[39]^: 227–8 and tried to install a pro-Thai king in Cambodia in the 1770s. In his final years there was a coup, caused supposedly by his "insanity", and eventually Taksin and his sons were executed by his longtime companion General Chao Phraya Chakri (the future Rama I). He was the first king of the ruling Chakri dynasty and founder of the Rattanakosin Kingdom on 6 April 1782.

Rattanakosin Kingdom

Under Rama I (1782–1809), Rattanakosin successfully defended against Burmese attacks and put an end to Burmese incursions. He also created suzerainty over large portions of Laos and Cambodia.[44] In 1821, Briton John Crawfurd was sent to negotiate a new trade agreement with Siam – the first sign of an issue which was to dominate 19th century Siamese politics.[45] Bangkok signed the Burney Treaty in 1826, after the British victory in the First Anglo-Burmese War.[39]^: 281 Anouvong of Vientiane, who mistakenly held the belief that Britain was about to launch an invasion of Bangkok, started the Lao rebellion in 1826 which was suppressed.[39]^: 283–5 Vientiane was destroyed and a large number of Lao people were relocated to Khorat Plateau as a result.[39]^: 285–6 Bangkok also waged several wars with Vietnam, where Siam successfully regained hegemony over Cambodia.[39]^: 290–2

From the late-19th century, Siam tried to rule the ethnic groups in the realm as colonies.[39]^: 308 In the reign of Mongkut (1851–1868), who recognised the potential threat Western powers posed to Siam, his court contacted the British government directly to defuse tensions.[39]^: 311 A British mission led by Sir John Bowring, Governor of Hong Kong, led to the signing of the Bowring Treaty, the first of many unequal treaties with Western countries. This, however, brought trade and economic development to Siam.[46] The unexpected death of Mongkut from malaria led to the reign of underage Prince Chulalongkorn, with Somdet Chaophraya Sri Suriwongse (Chuang Bunnag) acting as regent.[39]^: 327

Chulalongkorn (r. 1868–1910) initiated centralisation, set up a privy council, and abolished slavery and the corvée system. The Front Palace crisis of 1874 stalled attempts at further reforms.[39]^: 331–3 In the 1870s and 1880s, he incorporated the protectorates up north into the kingdom proper, which later expanded to the protectorates in the northeast and the south.[39]^: 334–5 He established twelve krom in 1888, which were equivalent to present-day ministries.[39]^: 347 The crisis of 1893 erupted, caused by French demands for Laotian territory east of Mekong.[39]^: 350–3 Thailand is the only Southeast Asian nation never to have been colonised by a Western power,[47] in part because Britain and France agreed in 1896 to make the Chao Phraya valley a buffer state.[48] Not until the 20th century could Siam renegotiate every unequal treaty dating from the Bowring Treaty, including extraterritoriality. The advent of the monthon system marked the creation of the modern Thai nation-state.[39]^: 362–3 In 1905, there were unsuccessful rebellions in the ancient Patani area, Ubon Ratchathani, and Phrae in opposition to an attempt to blunt the power of local lords.[39]^: 371–3

The Palace Revolt of 1912 was a failed attempt by Western-educated military officers to overthrow the Siamese monarchy.[39]^: 397 Vajiravudh (r. 1910–1925) responded by propaganda for the entirety of his reign,[39]^: 402 which promoted the idea of the Thai nation.[39]^: 404 In 1917, Siam joined the First World War on the side of the Allies.[39]^: 407 In the aftermath Siam had a seat at the Paris Peace Conference, and gained freedom of taxation and the revocation of extraterritoriality.[39]^: 408

Field Marshal Plaek Phibunsongkhram, the longest serving Prime Minister of Thailand

A bloodless revolution took place in 1932, in which Prajadhipok was forced to grant the country's first constitution, thereby ending centuries of feudal and absolute monarchy. The combined results of economic hardships brought on by the Great Depression, sharply falling rice prices, and a significant reduction in public spending caused discontent among aristocrats.[25]^: 25 In 1933, a counter-revolutionary rebellion occurred which aimed to reinstate absolute monarchy, but failed.[39]^: 446–8 Prajadhipok's conflict with the government eventually led to abdication. The government selected Ananda Mahidol, who was studying in Switzerland, to be the new king.[39]^: 448–9

Later that decade, the army wing of Khana Ratsadon came to dominate Siamese politics. Plaek Phibunsongkhram who became premier in 1938, started political oppression and took an openly anti-royalist stance.[39]^: 457 His government adopted nationalism and Westernisation, anti-Chinese and anti-French policies.[25]^: 28

In 1939, there was a decree changing the name of the country from "Siam" to "Thailand". In 1941, Thailand was in a brief conflict with Vichy France resulting in Thailand gaining some Lao and Cambodian territories.[39]^: 462

On 8 December 1941, the Empire of Japan launched an invasion of Thailand, and fighting broke out shortly before Phibun ordered an armistice. Japan was granted free passage, and on 21 December Thailand and Japan signed a military alliance with a secret protocol, wherein the Japanese government agreed to help Thailand regain lost territories.[49] The Thai government declared war on the United States and the United Kingdom.[39]^: 465 The Free Thai Movement was launched both in Thailand and abroad to oppose the government and Japanese occupation.[39]^: 465–6 After the war ended in 1945, Thailand signed formal agreements to end the state of war with the Allies. The main Allied powers had ignored Thailand's declaration of war.

King Bhumibol Adulyadej addresses a joint session of the United States Congress, 1960

In June 1946, young King Ananda was found dead under mysterious circumstances. His younger brother Bhumibol Adulyadej ascended to the throne. Thailand joined the Southeast Asia Treaty Organization (SEATO) to become an active ally of the United States in 1954.[39]^: 493 Field Marshal Sarit Thanarat launched a coup in 1957, which removed Khana Ratsadon from politics. His rule (premiership 1959–1963) was autocratic; he built his legitimacy around the god-like status of the monarch and by channelling the government's loyalty to the king.[39]^: 511 His government improved the country's infrastructure and education.[39]^: 514 After the United States joined the Vietnam War in 1961, there was a secret agreement wherein the U.S. promised to protect Thailand.[39]^: 523

The period brought about increasing modernisation and Westernisation of Thai society. Rapid urbanisation occurred when the rural populace sought work in growing cities. Rural farmers gained class consciousness and were sympathetic to the Communist Party of Thailand.[39]^: 528 Economic development and education enabled the rise of a middle class in Bangkok and other cities.[39]^: 534 In October 1971, there was a large demonstration against the dictatorship of Thanom Kittikachorn (premiership 1963–1973), which led to civilian casualties.[39]^: 541–3 Bhumibol installed Sanya Dharmasakti (premiership 1973–1975) to replace him, marking the first time that the king had intervened in Thai politics directly since 1932.[50] The aftermath of the event marked a short-lived parliamentary democracy,[50] often called the "era when democracy blossomed" (ยุคประชาธิปไตยเบ่งบาน).

Constant unrest and instability, as well as fear of a communist takeover after the fall of Saigon, made some ultra-right groups brand leftist students as communists.[39]^: 548 This culminated in the Thammasat University massacre in October 1976.[39]^: 548–9 A coup d'état on that day brought Thailand a new ultra-right government, which cracked down on media outlets, officials, and intellectuals, and fuelled the communist insurgency. Another coup the following year installed a more moderate government, which offered amnesty to communist fighters in 1978.[51]

Fuelled by Indochina refugee crisis, Vietnamese border raids and economic hardships, Prem Tinsulanonda became the Prime Minister from 1980 to 1988. The communists abandoned the insurgency by 1983. Prem's premiership was dubbed "semi-democracy" because the Parliament was composed of all elected House and all appointed Senate. The 1980s also saw increasing intervention in politics by the monarch, who rendered two coups in 1981 and 1985 attempts against Prem failed. Thailand had its first elected prime minister in 1988.[52]

Suchinda Kraprayoon, who was the coup leader in 1991 and said he would not seek to become prime minister,[53] was nominated as one by the majority coalition government after the 1992 general election. This caused a popular demonstration in Bangkok, which ended with a bloody military crackdown. Bhumibol intervened in the event and signed an amnesty law, Suchinda then resigned.[54]

United Front for Democracy Against Dictatorship, Red Shirts, protest in 2010

The 1997 Asian financial crisis originated in Thailand and ended the country's 40 years of uninterrupted economic growth.[55]^: 3 Chuan Leekpai's government took an IMF loan with unpopular provisions.[39]^: 576 The populist Thai Rak Thai party, led by prime minister Thaksin Shinawatra, governed from 2001 until 2006. His policies were successful in reducing rural poverty[56] and initiated universal healthcare in the country.[57] A South Thailand insurgency escalated starting from 2004. The 2004 Indian Ocean earthquake and tsunami hit the country, mostly in the south. Massive protests against Thaksin led by the People's Alliance for Democracy (PAD) started in his second term as prime minister and his tenure ended with a coup d'état in 2006. The junta installed a military government which lasted a year.[58]

In 2007, a civilian government led by the Thaksin-allied People's Power Party (PPP) was elected. Another protest led by PAD ended with the dissolution of PPP, and the Democrat Party led a coalition government in its place. The pro-Thaksin United Front for Democracy Against Dictatorship (UDD) protested both in 2009 and in 2010, the latter of which ended with a violent military crackdown causing more than 70 civilian deaths.[59]

After the general election of 2011, the populist Pheu Thai Party won a majority and Yingluck Shinawatra, Thaksin's younger sister, became prime minister. The People's Democratic Reform Committee organised another anti-Shinawatra protest[lower-alpha 8] after the ruling party proposed an amnesty bill which would benefit Thaksin.[60] Yingluck dissolved parliament and a general election was scheduled, but was invalidated by the Constitutional Court. The crisis ended with another coup d'état in 2014.

The ensuing National Council for Peace and Order, a military junta led by General Prayut Chan-o-cha, led the country until 2019. Civil and political rights were restricted, and the country saw a surge in lèse-majesté cases. Political opponents and dissenters were sent to "attitude adjustment" camps;[61] this was described by academics as showing the rise of fascism.[62] Bhumibol, the longest-reigning Thai king, died in 2016, and his son Vajiralongkorn ascended to the throne. The referendum and adoption of Thailand's current constitution happened under the junta's rule.[lower-alpha 9] The junta also bound future governments to a 20-year national strategy 'road map' it laid down, effectively locking the country into military-guided democracy.[64] In 2019, the junta agreed to schedule a general election in March.[61] Prayut continued his premiership with the support of Palang Pracharath Party-coalition in the House and junta-appointed Senate, amid allegations of election fraud.[65] The 2020–21 pro-democracy protests were triggered by increasing royal prerogative, democratic and economic regression from the Royal Thai Armed Forces supported by the Thai monarchy in the wake of the 2014 Thai coup d'état, dissolution of the pro-democracy Future Forward Party, distrust in the 2019 general election and the current political system, forced disappearance and deaths of political activists including Wanchalearm Satsaksit, and political corruption scandals,[66][67] which brought forward unprecedented demands to reform the monarchy[68] and the highest sense of republicanism in the country.[69]

In May 2023, Thailand’s reformist opposition,the progressive Move Forward Party (MFP) and the populist Pheu Thai Party, won the general election, meaning the royalist-military parties that supported Prime Minister Prayuth Chan-ocha lost power.[70] On 22 August 2023, Srettha Thavisin of the populist Pheu Thai party, became Thailand’s new prime minister, while the Pheu Thai party’s billionaire figurehead Thaksin Shinawatra returned to Thailand after years in self-imposed exile.[71]

Thailand map of Köppen climate classification.

Thailand's climate is influenced by monsoon winds that have a seasonal character (the southwest and northeast monsoon).[72]^: 2 Most of the country is classified as Köppen's tropical savanna climate.[73] The majority of the south as well as the eastern tip of the east have a tropical monsoon climate. Parts of the south also have a tropical rainforest climate.

A year in Thailand is divided into three seasons.[72]^: 2 The first is the rainy or southwest monsoon season (mid–May to mid–October), which is caused by southwestern wind from the Indian Ocean.[72]^: 2 Rainfall is also contributed by Intertropical Convergence Zone (ITCZ) and tropical cyclones,[72]^: 2 with August and September being the wettest period of the year.[72]^: 2 The country receives a mean annual rainfall of 1,200 to 1,600 mm (47 to 63 in).[72]^: 4 Winter or the northeast monsoon occurs from mid–October until mid–February.[72]^: 2 Most of Thailand experiences dry weather with mild temperatures.[72]^: 2, 4 Summer or the pre–monsoon season runs from mid–February until mid–May.[72]^: 3 Due to their inland position and latitude, the north, northeast, central and eastern parts of Thailand experience a long period of warm weather, where temperatures can reach up to 40 °C (104 °F) during March to May,[72]^: 3 in contrast to close to or below 0 °C (32 °F) in some areas in winter.[72]^: 3 Southern Thailand is characterised by mild weather year-round with less diurnal and seasonal variations in temperatures due to maritime influences.[72]^: 3 It receives abundant rainfall, particularly during October to November.[72]^: 2

Thailand is among the world's ten countries that are most exposed to climate change. In particular, it is highly vulnerable to rising sea levels and extreme weather events.[74][75]

The population of Asian elephants in Thailand's wild has dropped to an estimated 2,000–3,000.[76]

National parks in Thailand are defined as an area that contains natural resources of ecological importance or unique beauty, or flora and fauna of special importance. Thailand's protected areas include 156 national parks, 58 wildlife sanctuaries, 67 non-hunting areas, and 120 forest parks. They cover almost 31 per cent of the kingdom's territory.

The parks are administered by the National Parks, Wildlife and Plant Conservation Department (DNP), of the Ministry of Natural Resources and Environment (MNRE).

Thailand has a mediocre but improving performance in the global Environmental Performance Index (EPI) with an overall ranking of 91 out of 180 countries in 2016. The environmental areas where Thailand performs worst (i.e., highest-ranking) are air quality (167), environmental effects of the agricultural industry (106), and the climate and energy sector (93), the later mainly because of a high CO₂ emission per kWh produced. Thailand performs best (i.e., lowest-ranking) in water resource management (66), with some major improvements expected for the future, and sanitation (68).[77][78] The country had a 2019 Forest Landscape Integrity Index mean score of 6.00/10, ranking it 88th globally out of 172 countries.[79]

The population of elephants, the country's national symbol, has fallen from 100,000 in 1850 to an estimated 2,000.[76] Poachers have long hunted elephants for ivory and hides, and now increasingly for meat.[80] Young elephants are often captured for use in tourist attractions or as work animals, where there have been claims of mistreatment.[81] However, their use has declined since the government banned logging in 1989.

Poaching of protected species remains a major problem. Tigers, leopards, and other large cats are hunted for their pelts. Many are farmed or hunted for their meat, which supposedly has medicinal properties. Although such trade is illegal, the well-known Bangkok market Chatuchak is still known for the sale of endangered species.[82] The practice of keeping wild animals as pets affects species such as Asiatic black bear, Malayan sun bear, white-handed lar, pileated gibbon, and binturong.[83]

Thailand is a unitary state; the administrative services of the executive branch are divided into three levels by National Government Organisation Act, BE 2534 (1991): central, provincial and local. Thailand is composed of 76 provinces (จังหวัด, changwat),[103] which are first-level administrative divisions. There are also two specially governed districts: the capital Bangkok and Pattaya. Bangkok is at provincial level and thus often counted as a province. Each province is divided into districts (อำเภอ, amphoe) and the districts are further divided into sub-districts (ตำบล, tambons). The name of each province's capital city (เมือง, mueang) is the same as that of the province. For example, the capital of Chiang Mai Province (Changwat Chiang Mai) is Mueang Chiang Mai or Chiang Mai. All provincial governors and district chiefs, which are administrators of provinces and districts respectively, are appointed by the central government.[104] Thailand's provinces are sometimes grouped into four to six regions, depending on the source.

Siam's and Thailand's way of conducting foreign relations has long been described as "bamboo bending with the wind", which means adaptable and pragmatic. In order to secure independence, it sought to pit one great power against the others so that it would be dominated by none.[105]

During the Cold War, Thailand sought to prevent the spread of communism so it joined the United States, including participating in SEATO alliance, sending expeditions to Korea and Vietnam, and offering the US to use its base. Thailand is one of the five founding members of Association of Southeast Asian Nations (ASEAN), initially to safeguard against communism. The end of Vietnam War was a turning point in Thai foreign policy and afterwards it sought to improve relations with Communist China and its now-Communist neighbours. Thailand remains an active member of ASEAN and seek to project its influence in it. Thailand has developed increasingly close ties with other members, with progressing regional co-operation in economic, trade, banking, political, and cultural matters.[106]

In the 2000s, Thailand had taken an active role on the international stage and participated fully in international and regional organisations. It is a major non-NATO ally and Priority Watch List Special 301 Report of the United States. When East Timor gained independence from Indonesia, Thailand contributed troops to the international peacekeeping effort. As part of its effort to increase international ties, Thailand had reached out to such regional organisations as the Organization of American States (OAS) and the Organization for Security and Co-operation in Europe (OSCE).

During Thaksin Shinawatra's premiership, negotiations for several free trade agreements with China, Australia, Bahrain, India, and the US were initiated. Thaksin sought to position Thailand as a regional leader, initiating various development projects in poorer neighbouring countries. More controversially, he established close, friendly ties with the Burmese dictatorship.[107] Thailand joined the US-led invasion of Iraq, sending a humanitarian contingent until September 2004.[108] Thailand also had contributed troops to reconstruction efforts in Afghanistan.

In April 2009, the Cambodian–Thai border dispute brought troops on territory immediately adjacent to the 900-year-old ruins of Cambodia's Preah Vihear Hindu temple near the border.[109][110]

After the 2014 coup, Thailand leaned more towards China.[111] Growing Chinese influence and capital inflow caused some members of parliament to raise the concern about "economic colony" under China after many concessions.[112]

During the Israel-Hamas military conflict in 2023, at first Thailand's prime minister stated that his government strongly condemns the attack against Israel and extends its deepest condolences to the government and the people of Israel[113] but the government later changed its position and announced that Thailand adopted a neutral stance in this conflict.[114] 28 Thai nationals were killed in this conflict.[115]

The Royal Thai Armed Forces (กองทัพไทย; RTGS: Kong Thap Thai) constitute the military of the Kingdom of Thailand. It consists of the Royal Thai Army (กองทัพบกไทย), the Royal Thai Navy (กองทัพเรือไทย), and the Royal Thai Air Force (กองทัพอากาศไทย). It also incorporates various paramilitary forces.

The Thai Armed Forces have a combined manpower of 306,000 active duty personnel and another 245,000 active reserve personnel.[116] The head of the Thai Armed Forces (จอมทัพไทย, Chom Thap Thai) is the king,[117] although this position is only nominal. The armed forces are managed by the Ministry of Defence of Thailand, which is headed by the Minister of Defence (a member of the cabinet of Thailand) and commanded by the Royal Thai Armed Forces Headquarters, which in turn is headed by the Chief of Defence Forces of Thailand. Thai annual defense budget almost tripled from 78 billion baht in 2005 to 207 billion baht in 2016, accounting for approximately 1.5% of 2019 Thai GDP.[118] Thailand ranked 16th worldwide in the Military Strength Index based on the Credit Suisse report in September 2015.

The military is also tasked with humanitarian missions, such as escorting Rohingya to Malaysia or Indonesia,[119] ensuring security and welfare for refugees during Indochina refugee crisis.[120]

According to the constitution, serving in the armed forces is a duty of all Thai citizens.[121] Thailand still use active draft system for males over the age of 21. They are subjected to varying lengths of active service depending on the duration of reserve training as Territorial Defence Student and their level of education. Those who have completed three years or more of reserve training will be exempted entirely. The practice has long been criticized, as some media question its efficacy and value.[122][123] It is alleged that conscripts end up as servants to senior officers[124] or clerks in military cooperative shops.[125][126] In a report issued in March 2020, Amnesty International charged that Thai military conscripts face institutionalised abuse systematically hushed up by military authorities.[127]

Critics observed that Thai military's main objective is to deal with internal rather than external threats.[128] Internal Security Operations Command is called the political arm of the Thai military, which has overlapping social and political functions with civilian bureaucracy. It also has anti-democracy mission.[128] The military is also notorious for numerous corruption incidents, such as accusation of human trafficking,[129] and nepotism in promotion of high-ranking officers.[130] The military is deeply entrenched in politics. Most recently, the appointed senators include more than 100 active and retired military.[131]

In 2017, Thailand signed and ratified the UN Treaty on the Prohibition of Nuclear Weapons.[132]

Development of real GDP per capita, 1890 to 2018

Thais have median wealth per one adult person of $1,469 in 2016,[142]^: 98 increasing from $605 in 2010.[142]^: 34 In 2016, Thailand was ranked 87th in Human Development Index, and 70th in the inequality-adjusted HDI.[143]

In 2017, Thailand's median household income was ฿26,946 per month.[144]^: 1 Top quintile households had a 45.0% share of all income, while bottom quintile households had 7.1%.[144]^: 4 There were 26.9 million persons who had the bottom 40% of income earning less than ฿5,344 per person per month.[145]^: 5 During the 2013–2014 Thai political crisis, a survey found that anti-government PDRC mostly (32%) had a monthly income of more than ฿50,000, while pro-government UDD mostly (27%) had between ฿10,000 and ฿20,000.[146]^: 7

In 2014, Credit Suisse reported that Thailand was the world's third most unequal country, behind Russia and India.[147] The top 10% richest held 79% of the country's assets.[147] The top 1% held 58% of the assets.[147] The 50 richest Thai families had a total net worth accounting to 30% of GDP.[147] Bank of Thailand reported that during 2006–16, Thailand's top 5% largest companies had 85% of all corporate revenue in the nation, and only 6% of the country's companies were in export industries, which made up 60% of the country's GDP.[148]

In 2016, 5.81 million people lived in poverty, or 11.6 million people (17.2% of population) if "near poor" is included.[145]^: 1 The proportion of the poor relative to total population in each region was 12.96% in the Northeast, 12.35% in the South, and 9.83% in the North.[145]^: 2 In 2017, there were 14 million people who applied for social welfare (yearly income of less than ฿100,000 was required).[147] In the first quarter of 2023, Thai household debts totaled 14.6 trillion baht or 89.2% of GDP; the average debt per household was approximately 500,000 baht.[149] In 2016, there were estimated 30,000 homeless persons in the country.[150]

The economy of Thailand is heavily export-dependent, with exports accounting for more than two-thirds of gross domestic product (GDP). Thailand exports over US$105 billion worth of goods and services annually.[1] Major exports include cars, computers, electrical appliances, rice, textiles and footwear, fishery products, rubber, and jewellery.[1]

Substantial industries include electric appliances, components, computer components, and vehicles. Thailand's recovery from the 1997–1998 Asian financial crisis depended mainly on exports, among various other factors. As of 2012, the Thai automotive industry was the largest in Southeast Asia and the 9th largest in the world.[151][152][153] The Thailand industry has an annual output of near 1.5 million vehicles, mostly commercial vehicles.[153]

Most of the vehicles built in Thailand are developed and licensed by foreign producers, mainly Japanese and American. The Thai car industry takes advantage of the ASEAN Free Trade Area (AFTA) to find a market for many of its products. Eight manufacturers, five Japanese, two US, and Tata of India, produce pick-up trucks in Thailand.[154] As of 2012, due to its favorable taxation for 2-door pick-ups at only 3–12% against 17–50% for passenger cars, Thailand was the second largest consumer of pick-up trucks in the world, after the US.[155] In 2014, pick-ups accounted for 42% of all new vehicle sales in Thailand.[154]

Wat Arun, Bangkok is among the best known of Thailand's landmarks.

Tourism makes up about 6% of the country's economy. Prior to the pandemic, Thailand was world's eighth most visited country as per World Tourism rankings compiled by the United Nations World Tourism Organization. In 2019, Thailand received 39.8 million international tourists, ahead of United Kingdom and Germany[156] and received fourth highest international tourism earning at 60.5 billion US dollar.

Thailand was the most visited country in Southeast Asia in 2013, according to the World Tourism Organisation. Estimates of tourism receipts directly contributing to the Thai GDP of 12 trillion baht range from 9 per cent (1 trillion baht) (2013) to 16 per cent.[157] When including the indirect effects of tourism, it is said to account for 20.2 per cent (2.4 trillion baht) of Thailand's GDP.[158]^: 1

Asian tourists primarily visit Thailand for Bangkok and the historical, natural, and cultural sights in its vicinity. Western tourists not only visit Bangkok and surroundings; many travel to the southern beaches and islands. The north is the chief destination for trekking and adventure travel with its diverse ethnic minority groups and forested mountains. The region hosting the fewest tourists is Isan. To accommodate foreign visitors, a separate tourism police with offices were set up in the major tourist areas and an emergency telephone number.[159]

Thailand ranks fifth biggest medical tourism destination of inbound medical tourism spending, according to World Travel and Tourism Council, attracting over 2.5 million visitors in 2018.[160] The country is also Asia's number one.[161] The country is popular for the growing practice of sex reassignment surgery (SRS) and cosmetic surgery. In 2010–2012, more than 90% of medical tourists travelled to Thailand for SRS.[162]

Prostitution in Thailand and sex tourism also form a de facto part of the economy. Campaigns promote Thailand as exotic to attract tourists.[163] One estimate published in 2003 placed the trade at US$4.3 billion per year or about 3% of the Thai economy.[164] It is believed that at least 10% of tourist dollars are spent on the sex trade.[165]

Thailand has long been one of the largest rice exporters in the world. Forty-nine per cent of Thailand's labour force is employed in agriculture.[166]

Forty-nine per cent of Thailand's labour force is employed in agriculture.[166] This is down from 70% in 1980.[166] Rice is the most important crop in the country and Thailand had long been the world's leading exporter of rice, until recently falling behind both India and Vietnam.[167] Thailand has the highest percentage of arable land, 27.25%, of any nation in the Greater Mekong Subregion.[168] About 55% of the arable land area is used for rice production.[169]

Agriculture has been experiencing a transition from labour-intensive and transitional methods to a more industrialised and competitive sector.[166] Between 1962 and 1983, the agricultural sector grew by 4.1% per year on average and continued to grow at 2.2% between 1983 and 2007.[166] The relative contribution of agriculture to GDP has declined while exports of goods and services have increased.

Furthermore, access to biocapacity in Thailand is lower than world average. In 2016, Thailand had 1.2 global hectares[170] of biocapacity per person within its territory, a little less than world average of 1.6 global hectares per person.[171] In contrast, in 2016, they used 2.5 global hectares of biocapacity – their ecological footprint of consumption. This means they use about twice as much biocapacity as Thailand contains, resulting in a deficit.[170]

Thailand has a diverse and robust informal labour sector—in 2012, it was estimated that informal workers comprised 62.6% of the Thai workforce. The Ministry of Labour defines informal workers to be individuals who work in informal economies and do not have employee status under a given country's Labour Protection Act (LPA). The informal sector in Thailand has grown significantly over the past 60 years over the course of Thailand's gradual transition from an agriculture-based economy to becoming more industrialised and service-oriented.[172] Between 1993 and 1995, ten per cent of the Thai labour force moved from the agricultural sector to urban and industrial jobs, especially in the manufacturing sector. It is estimated that between 1988 and 1995, the number of factory workers in the country doubled from two to four million, as Thailand's GDP tripled.[173] While the Asian Financial Crisis that followed in 1997 hit the Thai economy hard, the industrial sector continued to expand under widespread deregulation, as Thailand was mandated to adopt a range of structural adjustment reforms upon receiving funding from the IMF and World Bank. These reforms implemented an agenda of increased privatisation and trade liberalisation in the country, and decreased federal subsidisation of public goods and utilities, agricultural price supports, and regulations on fair wages and labour conditions.[174] These changes put further pressure on the agricultural sector, and prompted continued migration from the rural countryside to the growing cities. Many migrant farmers found work in Thailand's growing manufacturing industry, and took jobs in sweatshops and factories with few labour regulations and often exploitative conditions.[175]

Those that could not find formal factory work, including illegal migrants and the families of rural Thai migrants that followed their relatives to the urban centres, turned to the informal sector to provide the extra support needed for survival—under the widespread regulation imposed by the structural adjustment programs, one family member working in a factory or sweatshop made very little. Scholars argue that the economic consequences and social costs of Thailand's labour reforms in the wake of the 1997 Asian Financial Crisis fell on individuals and families rather than the state: as the country's labour market became increasingly deregulated, the burden and responsibility of providing an adequate livelihood shifted from employers and the state to the workers themselves, whose families had to find jobs in the informal sector to make up for the losses and subsidise the wages being made by their relatives in the formal sector. The weight of these economic changes hit migrants and the urban poor especially hard, and the informal sector expanded rapidly as a result.[174]

Songkran Festival, Chiang Mai's ancient city wall

Today, informal labour in Thailand is typically broken down into three main groups: subcontracted/self employed/home-based workers, service workers (including those that are employed in restaurants, as street vendors, masseuses, taxi drivers, and as domestic workers), and agricultural workers. Not included in these categories are those that work in entertainment, nightlife, and the sex industry. Individuals employed in these facets of the informal labour sector face additional vulnerabilities, including recruitment into circles of sexual exploitation and human trafficking.[172] A 2012 study found that 64% of informal workers had not completed education beyond primary school. Many informal workers are also migrants, only some of which have legal status in the country. Because the informal labour sector is not recognised under the Labour Protection Act (LPA), informal workers are much more vulnerable to exploitation and unsafe working conditions. While some Thai labour laws provide minimal protections to domestic and agricultural workers, they are often weak and difficult to enforce. Furthermore, Thai social security policies fail to protect against the risks many informal workers face, including workplace accidents and compensation as well as unemployment and retirement insurance. Many informal workers are not legally contracted for their employment, and many do not make a living wage.[172] Tens of thousands of migrants from neighboring countries face exploitation in a few industries,[176] especially in fishing where slave-like conditions have been reported.[177]

Thailand ranked 43rd in the Global Innovation Index in 2023.[178] The Ministry of Higher Education, Science, Research and Innovation and its agencies oversees the development of science, technology, and research in Thailand. According to the National Research Council of Thailand, the country devoted 1.1% of its GDP to the research and development of science in 2019, with over 166,788 research and development personnel in full-time equivalent that year.[179][180]

The BTS Skytrain is an elevated rapid transit system in Bangkok.

There were two failed project Lavalin Skytrain and Bangkok Elevated Road and Train System , before Mass Rapid Transit Master Plan in Bangkok Metropolitan Region endorsed by the cabinet on 27 September 1994 and to be implemented from 1995 to 2011.

The State Railway of Thailand (SRT) operates all of Thailand's national rail lines. Krung Thep Aphiwat Central Terminal and Bangkok (Hua Lamphong) are the main termini of intercity routes. Phahonyothin and ICD Lat Krabang are the main freight terminals. As of 2017 SRT had 4,507 km (2,801 mi) of track, all of it meter gauge. Nearly all is single-track (4,097 km), although some important sections around Bangkok are double (303 km or 188 mi) or triple-tracked (107 km or 66 mi) and there are plans to extend this.[181] Rail transport in Bangkok includes long-distance services, and some daily commuter trains running from and to the outskirts of the city during the rush hour, but passenger numbers have remained low. There are also four rapid transit rail systems in the capital: the BTS Skytrain, MRT, SRT Red Lines and the Airport Rail Link.

Thailand has 390,000 kilometres (240,000 miles) of highways.[182] As of 2017, Thailand has over 462,133 roads and 37 million registered vehicles, 20 million of them motorbikes.[183] A number of undivided two-lane highways have been converted into divided four-lane highways. Within the Bangkok Metropolitan Region, there are a number of controlled-access highways. There are 4,125 public vans operating on 114 routes from Bangkok alone.[184] Other forms of road transport includes tuk-tuks, taxis—with over 80,647 registered taxis nationwide as of 2018[185]—vans (minibus), motorbike taxis and songthaews.

As of 2012, Thailand has 103 airports with 63 paved runways, in addition to 6 heliports. The busiest airport in the country is Bangkok's Suvarnabhumi Airport.

75% of Thailand's electrical generation is powered by natural gas in 2014.[186] Coal-fired power plants produce an additional 20% of electricity, with the remainder coming from biomass, hydro, and biogas.[186]

Thailand produces roughly one-third of the oil it consumes. It is the second largest importer of oil in SE Asia. Thailand is a large producer of natural gas, with reserves of at least 10 trillion cubic feet. After Indonesia, it is the largest coal producer in SE Asia, but must import additional coal to meet domestic demand.

Thai nationals make up the majority of Thailand's population, 95.9% in 2010. The remaining 4.1% of the population are Burmese (2.0%), others 1.3%, and unspecified 0.9%.[1]

According to the Royal Thai Government's 2011 Country Report to the UN Committee responsible for the International Convention for the Elimination of All Forms of Racial Discrimination, available from the Department of Rights and Liberties Promotion of the Thai Ministry of Justice,^: 3 62 ethnic communities are officially recognised in Thailand. Twenty million Central Thai (together with approximately 650,000 Khorat Thai) make up approximately 20,650,000 (34.1 per cent) of the nation's population of 60,544,937[189] at the time of completion of the Mahidol University Ethnolinguistic Maps of Thailand data (1997).[190]

The 2011 Thailand Country Report provides population numbers for mountain peoples ('hill tribes') and ethnic communities in the Northeast and is explicit about its main reliance on the Mahidol University Ethnolinguistic Maps of Thailand data.[190] Thus, though over 3.288 million people in the Northeast alone could not be categorised, the population and percentages of other ethnic communities c. 1997 are known for all of Thailand and constitute minimum populations. In descending order, the largest (equal to or greater than 400,000) are a) 15,080,000 Lao (24.9 per cent) consisting of the Thai Lao (14 million) and other smaller Lao groups, namely the Thai Loei (400–500,000), Lao Lom (350,000), Lao Wiang/Klang (200,000), Lao Khrang (90,000), Lao Ngaew (30,000), and Lao Ti (10,000); b) six million Khon Muang (9.9 per cent, also called Northern Thais); c) 4.5 million Pak Tai (7.5 per cent, also called Southern Thais); d) 1.4 million Khmer Leu (2.3 per cent, also called Northern Khmer); e) 900,000 Malay (1.5%); f) 500,000 Nyaw (0.8 per cent); g) 470,000 Phu Thai (0.8 per cent); h) 400,000 Kuy/Kuay (also known as Suay) (0.7 per cent), and i) 350,000 Karen (0.6 per cent).^: 7–13 Thai Chinese, those of significant Chinese heritage, are 14% of the population, while Thais with partial Chinese ancestry comprise up to 40% of the population.[191] Thai Malays represent 3% of the population, with the remainder consisting of Mons, Khmers and various "hill tribes".

Increasing numbers of migrants from neighbouring Myanmar, Laos, and Cambodia, as well as from Nepal and India, have pushed the total number of non-national residents to around 3.5 million as of 2009, up from an estimated 2 million in 2008.[192] Some 41,000 Britons and 20,000 Australians live in Thailand.[193][194]

The Silajaruek of Sukhothai Kingdom are hundreds of stone inscriptions that form a historical record of the period.

The official language of Thailand is Thai, a Kra–Dai language closely related to Lao, Shan in Myanmar, and numerous smaller languages spoken in an arc from Hainan and Yunnan south to the Chinese border. It is the principal language of education and government and spoken throughout the country. The standard is based on the dialect of the central Thai people, and it is written in the Thai alphabet, an abugida script that evolved from the Khmer alphabet. Sixty-two languages were recognised by the Royal Thai Government. For the purposes of the national census, four dialects of Thai exist; these partly coincide with regional designations, such as Southern Thai and Northern Thai.

The largest of Thailand's minority languages is the Lao dialect of Isan spoken in the northeastern provinces. In the far south, Kelantan-Pattani Malay is the primary language of Malay Muslims. Varieties of Chinese are also spoken by the large Thai Chinese population, with the Teochew dialect best-represented. Numerous tribal languages are also spoken, including many Austroasiatic languages such as Mon, Khmer, Viet, Mlabri and Aslian; Austronesian languages such as Cham, Moken and Urak Lawoi'; Sino-Tibetan languages like Lawa, Akha, and Karen; and other Tai languages such as Tai Yo, Phu Thai, and Saek. Hmong is a member of the Hmong–Mien languages, which is now regarded as a language family of its own.

The country's most prevalent religion is Theravada Buddhism, which is an integral part of Thai identity and culture. Active participation in Buddhism is among the highest in the world. Thailand has the second-largest number of Buddhists in the world after China.[196] According to the 2000 census, 94.6% and 93.58% in 2010 of the country's population self-identified as Buddhists of the Theravada tradition.

Samanera of Theravada Buddhism, the most practised religion in Thailand.

Muslims constitute the second largest religious group in Thailand, comprising 5.4% of the population in 2018.[197] Islam is concentrated mostly in the country's southernmost provinces: Pattani, Yala, Satun, Narathiwat, and part of Songkhla Chumphon, which are predominantly Malay, most of whom are Sunni Muslims. Christians represented 1.13% (2018) of the population in 2018, with the remaining population consisting of Hindus and Sikhs, who live mostly in the country's cities. There is also a small but historically significant Jewish community in Thailand dating back to the 17th century.

The constitution does not name an official state religion, and provides for freedom of religion. There have been no widespread reports of societal abuses or discrimination based on religious belief or practice.[198] Thai law officially recognizes five religious groups: Buddhists, Muslims, Brahmin-Hindus, Sikhs, and Christians.[199] However, some laws are inspired from Buddhist practices, such as banning alcohol sales on religious holidays.[200]

Chulalongkorn University, established in 1917, is the oldest university in Thailand.

In 1995, as minister of education,Sukavich Rangsitpollaid out his plans for educational reform in Thailand. The goal of education reform is to realize the potential of Thai people to develop themselves for the better quality of life and to develop the nation for peaceful co-existence in the world community.[201] The reform was considered a landmark movement after nearly 100 years of education under the previous system.[202]

Thailand's youth literacy rate was 98.1% in 2015.[203] Education is provided by a well-organised school system of kindergartens, primary, lower secondary and upper secondary schools, numerous vocational colleges, and universities. Education is compulsory up to and including age 14, while the government is mandated to provide free education through to age 17. The establishment of reliable and coherent curricula for its primary and secondary schools is subject to rapid changes. Issues concerning university entrance has been in constant upheaval for a number of years. The country is also one of the few that still mandates uniform up to the university years, which is still a subject of ongoing debate. The quality of education in the country is often questioned.

In 2013, the Ministry of Information and Communication Technology announced that 27,231 schools would receive classroom-level access to high-speed internet.[204] However, the country's educational infrastructure was still underprepared for online teaching, as smaller and more remote schools were particularly hindered by COVID-19 restrictions.[205]

The number of higher education institutions in Thailand has grown over the past decades to 156 officially. The two top-ranking universities in Thailand are Chulalongkorn University and Mahidol University.[206] Thai universities' research output is still relatively low, even though the country's journal publications increased by 20% between 2011 and 2016.[207] Recent initiatives, such as the National Research University[208] and Graduate research intensive university: VISTEC, are designed to strengthen Thailand's national research universities.

The private sector of education is well developed and significantly contributes to the overall provision of education. Thailand has the second highest number of English-medium private international schools in Southeast Asian Nations.[209] Cram schools are especially popular for university entrance exams.

Students in ethnic minority areas score consistently lower in standardised national and international tests.[210][211][212] This is likely due to unequal allocation of educational resources, weak teacher training, poverty, and low Thai language skill, the language of the tests.[210][213][214] As of 2020, Thailand was ranked 89th out of 100 countries globally for English proficiency.[215]

Thailand is the third most popular study destination in ASEAN. The number of international degree students in Thailand increased by 9.7 times between 1999 and 2012, from 1,882 to 20,309 students. Most of international students come from neighbor countries[209] like China, Myanmar, Cambodia and Vietnam.[216]

Siriraj Hospital in Bangkok, the oldest and largest hospital in Thailand.

Thailand ranks world's sixth, and Asia's first in the 2019 Global Health Security Index of global health security capabilities in 195 countries,[217] making it the only developing country on the world's top ten. Thailand had 62 hospitals accredited by Joint Commission International.[218] In 2002, Bumrungrad became the first hospital in Asia to meet the standard.

Health and medical care is overseen by the Ministry of Public Health (MOPH), with total national expenditures on health amounting to 4.3 per cent of GDP in 2009. Non-communicable diseases form the major burden of morbidity and mortality, while infectious diseases including malaria and tuberculosis, as well as traffic accidents, are also important public health issues.

In December 2018 the interim parliament voted to legalise the use of cannabis for medical reasons, making Thailand the first Southeast Asian country to allow the use of medical cannabis.[219]

Scene from the Ramakien depicted on a mural at Wat Phra Kaew.

The origins of Thai art were very much influenced by Buddhist art and by scenes from the Indian epics. Traditional Thai sculpture almost exclusively depicts images of the Buddha, being very similar with the other styles from Southeast Asia. Traditional Thai paintings usually consist of book illustrations, and painted ornamentation of buildings such as palaces and temples. Thai art was influenced by indigenous civilisations of the Mon and other civilisations. By the Sukothai and Ayutthaya period, Thai had developed into its own unique style and was later further influenced by the other Asian styles, mostly by Sri Lankan and Chinese. Thai sculpture and painting, and the royal courts provided patronage, erecting temples and other religious shrines as acts of merit or to commemorate important events.[221]

Traditional Thai paintings showed subjects in two dimensions without perspective. The size of each element in the picture reflected its degree of importance. The primary technique of composition is that of apportioning areas: the main elements are isolated from each other by space transformers. This eliminated the intermediate ground, which would otherwise imply perspective. Perspective was introduced only as a result of Western influence in the mid-19th century. Monk artist Khrua In Khong is well known as the first artist to introduce linear perspective to Thai traditional art.[222]

The most frequent narrative subjects for paintings were or are: the Jataka stories, episodes from the life of the Buddha, the Buddhist heavens and hells, themes derived from the Thai versions of the Ramayana and Mahabharata, and scenes of daily life. Some of the scenes are influenced by Thai folklore instead of following strict Buddhist iconography.[221]

Architecture is the preeminent medium of the country's cultural legacy and reflects both the challenges of living in Thailand's sometimes extreme climate as well as, historically, the importance of architecture to the Thai people's sense of community and religious beliefs. Influenced by the architectural traditions of many of Thailand's neighbours, it has also developed significant regional variation within its vernacular and religious buildings.

The Ayutthaya Kingdom movement was one of the most fruitful and creative periods in Thai architecture. Architecture in the Ayutthaya period is designed to display might and riches so it has great size and appearance. The temples in Ayutthaya seldom built eaves stretching from the masterhead. The dominant feature of this style is sunlight shining into buildings. During the latter part of the Ayutthaya period, architecture was regarded as a peak achievement that responded to the requirements of people and expressed the gracefulness of Thainess.[223]

Buddhist temples in Thailand are known as "wats", from the Pāḷi vāṭa, meaning an enclosure: a temple has an enclosing wall that divides it from the secular world. Wat architecture demonstrates many differences in layout and style, but they all adhere to the same principles.[224]

Thai literature has had a long history. Even before the establishment of the Sukhothai Kingdom there existed oral and written works.

During the Sukhothai Kingdom, most literary works were written in simple prose with certain alliteration schemes. Major works include King Ram Khamhaeng Inscription describing life at the time, which is considered the first literary work in Thai script, but some historians questioned its authenticity.[225] Trai Phum Phra Ruang, written in 1345 by King Maha Thammaracha I, expounds Buddhist philosophy based on a profound and extensive study with reference to over 30 sacred texts and could be considered the nation's first piece of research dissertation.[226]

During the Ayutthaya Kingdom, new poetic forms were created, with different rhyme schemes and metres. It is common to find a combination of different poetic forms in one poetic work. Lilit Yuan Phai is a narrative poem describing the war between King Borommatrailokkanat of Ayutthaya and Prince Tilokkarat of Lan Na. One of the most beautiful literary works is Kap He Ruea composed by Prince Thammathibet in the nirat tradition. Traditionally, the verse is sung during the colourful royal barge procession and has been the model for subsequent poets to emulate. The same prince also composed the greatly admired Kap Ho Khlong on the Visit to Than Thongdaeng and Kap Ho Khlong Nirat Phrabat.[227] The Thon Buri Period produced Ramakian, a verse drama contributed by King Taksin the Great. The era marked the revival of literature after the fall of Ayutthaya.

During the 18th century Rattanakosin period, which still fought with the Burmese, many of the early Rattanakosin works deal with war and military strategy. Some examples are Nirat Rop Phama Thi Tha Din Daeng, Phleng Yao Rop Phama Thi Nakhon Si Thammarat. In the performing arts, perhaps the most important dramatic achievement is the complete work of Ramakian by King Rama I. In addition, There were also verse recitals with musical accompaniment, such as Mahori telling the story of Kaki, Sepha relating the story of Khun Chang Khun Phaen. Other recitals include Sri Thanonchai. The most important Thai poet in this period was Sunthorn Phu (สุนทรภู่), known as "the bard of Rattanakosin" (Thai: กวีเอกแห่งกรุงรัตนโกสินทร์). Sunthorn Phu is best known for his epic poem Phra Aphai Mani, a versified fantasy-adventure novel, a genre of Siamese literature known as nithan kham klon (Thai: นิทานคำกลอน).[227]

Some of the most well-known modern Thai writers include Kukrit Pramoj, Kulap Saipradit, (penname Siburapha), Suweeriya Sirisingh (penname Botan), Chart Korbjitti, Prabda Yoon and Duanwad Pimwana.[228]

Khon show is the most stylised form of Thai performance.

Aside from folk and regional dances (southern Thailand's Menora (dance) and Ramwong, for example), the two major forms of Thai classical dance drama are Khon and Lakhon nai. In the beginning, both were exclusively court entertainments and it was not until much later that a popular style of dance theatre, likay, evolved as a diversion for common folk.[229]

Folk dance forms include dance theater forms like likay, numerous regional dances (ram), the ritual dance ram muay, and homage to the teacher, wai khru. Both ram muay and wai khru take place before all traditional muay Thai matches. The wai is also an annual ceremony performed by Thai classical dance groups to honor their artistic ancestors.

Thai classical music is synonymous with those stylized court ensembles and repertoires that emerged in their present form within the royal centers of Central Thailand some 800 years ago. These ensembles, while being influenced by older practices are today uniquely Thai expressions. While the three primary classical ensembles, the Piphat, Khrueang sai and Mahori differ in significant ways, they all share a basic instrumentation and theoretical approach. Each employs small ching hand cymbals and krap wooden sticks to mark the primary beat reference. Thai classical music has had a wide influence on the musical traditions of neighboring countries.

Thai cuisine is one of the most popular in the world.[238][239] Thai food blends five fundamental tastes: sweet, spicy, sour, bitter, and salty. Common ingredients include garlic, lemongrass, kaffir lime, galangal, turmeric, coriander, and coconut milk.[240] Each region of Thailand has its specialities: kaeng khiao wan (green curry) in the central region, som tam (green papaya salad) in the northeast, khao soi in the north, and massaman curry in the south.

In 2017, seven Thai dishes appeared on a list of the "World's 50 Best Foods"— an online worldwide poll by CNN Travel. Thailand had more dishes on the list than any other country. They were: tom yam goong (4th), pad Thai (5th), som tam (6th), massaman curry (10th), green curry (19th), Thai fried rice (24th) and mu nam tok (36th).[241] Two desserts were also listed in CNN’s 50 Best Desserts Around The World: mango sticky rice and tub tim krob.[242]

The staple food in Thailand is rice, particularly jasmine rice, which forms part of almost every meal. Thailand is a leading exporter of rice, and Thais consume over 100 kg of milled rice per person per year.[243] Thailand is also the world leader in edible insect industry[244] and well-known for its street food; Bangkok is sometimes called the street food capital of the world.[245][246]

Thailand generally uses the metric system, but traditional units of measurement for land area are used, and imperial units of measurement are occasionally used for building materials. Years are numbered as B.E. (Buddhist Era) in educational settings, civil service, government, contracts, and newspaper datelines. However, in banking, and increasingly in industry and commerce, standard Western year (Christian or Common Era) counting is the standard practice.[247]

Muay Thai, Thailand's signature sport

Muay Thai (lit. "Thai boxing") is a combat sport that uses stand-up striking along with various clinching techniques. Muay Thai became widespread internationally in the late-20th to 21st century. Famous practitioners include Buakaw Banchamek, Samart Payakaroon, Dieselnoi Chor Thanasukarn and Apidej Sit-Hirun. Buakaw Banchamek has probably brought more international interest in Muay Thai than any other fighter.[248]

Association football has overtaken Muay Thai as the most widely followed sport in Thailand. The Thailand national football team has played the AFC Asian Cup six times and reached the semifinals in 1972. The country has hosted the Asian Cup twice, in 1972 and in 2007. The 2007 edition was co-hosted together with Indonesia, Malaysia and Vietnam. Another widely enjoyed pastime, and once a competitive sport, is kite flying.

Volleyball is rapidly growing as one of the most popular sports. The women's team has often participated in the World Championship, World Cup, and World Grand Prix Asian Championship. They have won the Asian Championship twice and Asian Cup once. By the success of the women's team, the men's team has been growing as well.

Takraw (Thai: ตะกร้อ) is a sport native to Thailand, in which the players hit a rattan ball and are only allowed to use their feet, knees, chest, and head to touch the ball. Sepak takraw is a form of this sport which is similar to volleyball. A rather similar game but played only with the feet is buka ball.

Snooker has enjoyed increasing popularity in Thailand in recent years, with interest in the game being stimulated by the success of Thai snooker player James Wattana in the 1990s.[249] Other notable Thai players include Ratchayothin Yotharuck, Noppon Saengkham and Dechawat Poomjaeng.[250]

Rugby is also a growing sport in Thailand with the Thailand national rugby union team rising to be ranked 61st in the world.[251] Thailand became the first country in the world to host an international 80 welterweight rugby tournament in 2005.[252] The national domestic Thailand Rugby Union (TRU) competition includes several universities as well as local sports clubs like the British Club of Bangkok, the Southerners Sports Club (Bangkok) and the Royal Bangkok Sports Club.

Thailand has been called the golf capital of Asia.[253] The country attracts a large number of golfers from Japan, Korea, Singapore, South Africa, and Western countries.[254] The growing popularity of golf, especially among the middle classes and immigrants, is evident as there are more than 200 world-class golf courses nationwide,[255] and some of them are chosen to host PGA and LPGA tournaments, such as Amata Spring Country Club, Alpine Golf and Sports Club, Thai Country Club, and Black Mountain Golf Club.

Basketball is a growing sport in Thailand, especially on the professional sports club level. The Chang Thailand Slammers won the 2011 ASEAN Basketball League Championship.[256] The Thailand national basketball team had its most successful year at the 1966 Asian Games where it won the silver medal.[257]

Other sports in Thailand are slowly growing as the country develops its sporting infrastructure. The success in sports like weightlifting and taekwondo at the last two summer Olympic Games has demonstrated that boxing is no longer the only medal option for Thailand.
