Java

The 9th century Borobudur Buddhist stupa in Central Java

The Taruma and Sunda kingdoms of western Java appeared in the 4th and 7th centuries respectively, while the Kalingga Kingdom sent embassies to China starting in 640.[33]^: 53, 79 However, the first major principality was the Mataram Kingdom that was founded in central Java at the beginning of the 8th century. Mataram's religion centered on the Hindu god Shiva, and the kingdom produced some of Java's earliest Hindu temples on the Dieng Plateau. Around the 8th century, the Sailendra dynasty rose in Kedu Plain and become the patron of Mahayana Buddhism. This ancient kingdom built monuments such as the 9th century Borobudur and Prambanan in central Java.

Around the 10th century, the center of power shifted from central to eastern Java. The eastern Javanese kingdoms of Kediri, Singhasari and Majapahit were mainly dependent on rice agriculture, yet also pursued trade within the Indonesian archipelago, and with China and India. Majapahit was established by Wijaya,[33]^: 201 and by the end of the reign of Hayam Wuruk (r. 1350–89) it claimed sovereignty over the entire Indonesian archipelago, although control was likely limited to Java, Bali, and Madura. Hayam Wuruk's prime minister, Gajah Mada, led many of the kingdom's territorial conquests.[33]^: 234 Previous Javanese kingdoms had their power based on agriculture, however, Majapahit took control of ports and shipping lanes and became Java's first commercial empire. With the death of Hayam Wuruk and the coming of Islam to Indonesia, Majapahit went into decline.[33]^: 241

Islam became the dominant religion in Java at the end of the 16th century. During this era, the Islamic kingdoms of Demak, Cirebon, and Banten were ascendant. The Mataram Sultanate became the dominant power of central and eastern Java at the end of the 16th century. The principalities of Surabaya and Cirebon were eventually subjugated such that only Mataram and Banten were left to face the Dutch in the 17th century.

Java's contact with the European colonial powers began in 1522 with a treaty between the Sunda kingdom and the Portuguese in Malacca. After its failure, the Portuguese presence was confined to Malacca and to the eastern islands. In 1596, a four-ship expedition led by Cornelis de Houtman was the first Dutch contact with Indonesia.[34] By the end of the 18th century the Dutch had extended their influence over the sultanates of the interior through the Dutch East India Company in Indonesia. Internal conflict prevented the Javanese from forming effective alliances against the Dutch. Remnants of the Mataram survived as the Surakarta (Solo) and Yogyakarta principalities. Javanese kings claimed to rule with divine authority and the Dutch helped them to preserve remnants of a Javanese aristocracy by confirming them as regents or district officials within the colonial administration.

Java's major role during the early part of the colonial period was as a producer of rice. In spice-producing islands like Banda, rice was regularly imported from Java, to supply the deficiency in means of subsistence.[35]

During the Napoleonic wars in Europe, the Netherlands fell to France, as did its colony in the East Indies. During the short-lived Daendels administration, as French proxy rule on Java, the construction of the Great Post Road was commenced in 1808. The road, spanning from Anyer in Western Java to Panarukan in East Java, served as a military supply route and was used in defending Java from British invasion.[36] In 1811, Java was captured by the British, becoming a possession of the British Empire, and Sir Stamford Raffles was appointed as the island's governor. In 1814, Java was returned to the Dutch under the terms of the Treaty of Paris.[37]

In 1815, there may have been five million people in Java.[38] In the second half of the 18th century, population spurts began in districts along the north-central coast of Java, and in the 19th century population grew rapidly across the island. Factors for the great population growth include the impact of Dutch colonial rule including the imposed end to civil war in Java, the increase in the area under rice cultivation, and the introduction of food plants such as cassava and maize that could sustain populations that could not afford rice.[39] Others attribute the growth to the taxation burdens and increased expansion of employment under the Cultivation System to which couples responded by having more children in the hope of increasing their families ability to pay tax and buy goods.[40] Cholera claimed 100,000 lives in Java in 1820.[41]

The advent of trucks and railways where there had previously only been buffalo and carts, telegraph systems, and more coordinated distribution systems under the colonial government all contributed to famine elimination in Java, and in turn, population growth. There were no significant famines in Java from the 1840s through to the Japanese occupation in the 1940s.[42] However, other sources claimed the Dutch's Cultivation system is linked to famines and epidemics in the 1840s, firstly in Cirebon and then Central Java, as cash crops such as indigo and sugar had to be grown instead of rice.

Indonesian nationalism first took hold in Java in the early 20th century, and the struggle to secure the country's independence following World War II was centered in Java. In 1949, Indonesian independence was recognized.

Jakarta, the capital of Indonesia

Java has been traditionally dominated by an elite class, while the people in the lower classes were often involved in agriculture and fishing. The elite class in Java has evolved over the course of history, as cultural wave after cultural wave immigrated to the island. There is evidence that South Asian emigres were among this elite, as well as Arabian and Persian immigrants during the Islamic eras. More recently, Chinese immigrants have also become part of the economic elite of Java. Although politically the Chinese generally remain sidelined, there are notable exceptions, such as the former governor of Jakarta, Basuki Tjahaja Purnama. Though Java is increasingly becoming more modern and urban, only 75% of the island has electricity. Villages and their rice paddies are still a common sight. Unlike the rest of Java, the population growth in Central Java remains low. Central Java however has a younger population than the national average.[46] The slow population growth can in part be attributed to the choice by many people to leave the more rural Central Java for better opportunities and higher incomes in the bigger cities.[47] Java's population continues to rapidly increase despite many Javanese leaving the island. This is somewhat due to the fact that Java is the business, academic, and cultural hub of Indonesia, which attracts millions of non-Javanese people to its cities. The population growth is most intense in the regions surrounding Jakarta and Bandung, which is reflected through the demographic diversity in those areas.

With a combined population of 151.6 million in the 2020 census (including Madura's 4.0 million),[48] Java is the most populous major island in the world and is home to 56% of Indonesia's population.[48] At nearly 1,200 people per km² in 2020, it is also one of the most densely populated parts of the world, on a par with Bangladesh. Every region of the island has numerous volcanoes, with the people left to share the remaining flatter land. Because of this, many coasts are heavily populated and cities ring around the valleys surrounding volcanic peaks.

The population growth rate more than doubled in economically depressed Central Java in the latest 2010–2020 period vs 2000–2010, indicative of migration or other issues; there were significant volcanic eruptions during the earlier period. Approximately 45% of the population of Indonesia is ethnically Javanese,[49] while Sundanese make a large portion of Java's population as well.

The western third of the island (West Java, Banten, and DKI Jakarta) has an even higher population density, of roughly 1,563 per square kilometer and accounts for the lion's share of the population growth of Java.[48] It is home to three metropolitan areas, Greater Jakarta (with outlying areas of Greater Serang and Greater Sukabumi), Greater Bandung, and Greater Cirebon.

From the 1970s to the fall of the Suharto regime in 1998, the Indonesian government ran transmigration programs aimed at resettling the population of Java on other less populated islands of Indonesia. This program has met with mixed results, sometimes causing conflicts between the locals and the recently arrived settlers. Nevertheless, it has caused Java's share of the nation's population to progressively decline.

Jakarta and its outskirts, being the dominant metropolis, is also home to people from all over the nation. East Java is also home to ethnic Balinese, as well as large numbers of Madurans due to their historic poverty.

Despite its large population and in contrast to the other larger islands of Indonesia, Java is comparatively homogeneous in ethnic composition. Only two ethnic groups are native to the island—the Javanese and Sundanese. A third group is the Madurese, who inhabit the island of Madura off the northeast coast of Java, and have immigrated to East Java in large numbers since the 18th century.[54] The Javanese comprise about two-thirds of the island's population, while the Sundanese and Madurese account for 38% and 10% respectively.[54] The fourth group is the Betawi people that speak a dialect of Malay, they are the descendants of the people living around Batavia from around the 17th century. Betawis are creole people, mostly descended from various Indonesian archipelago ethnic groups such as Malay, Sundanese, Javanese, Balinese, Minang, Bugis, Makassar, Ambonese, mixed with foreign ethnic groups such as Portuguese, Dutch, Arab, Chinese and Indian brought to or attracted to Batavia to meet labour needs. They have a culture and language distinct from the surrounding Sundanese and Javanese.

The Javanese prose text Tantu Pagelaran (circa 15th century) explained the mythical origin of the island and its volcanic nature.

Four major cultural areas exist on the island: the central part of Java or Yogyakarta is the Javanese people heartland and the north coast of the pasisir region, the Sunda lands (Sundanese: ᮒᮒᮁ ᮞᮥᮔ᮪ᮓ, Tatar Sunda) in the western part of Java and Parahyangan as the heartland, the eastern salient of Java also known as Blambangan. Madura makes up a fifth area having close cultural ties with coastal eastern Java.[54] The kejawen of Javanese culture is the island's most dominant. Java's remaining aristocracy is based here, and it is the region from where the majority of Indonesia's army, business, and political elite originate. Its language, arts, and etiquette are regarded as the island's most refined and exemplary.[54] The territory from Banyumas in the west through to Blitar in the east and encompasses Indonesia's most fertile and densely populated agricultural land.[54]

In the southwestern part of Central Java, which is usually named the Banyumasan region, a cultural mingling occurred; bringing together Javanese culture and Sundanese culture to create the Banyumasan culture.[55] In the central Javanese court cities of Yogyakarta and Surakarta, contemporary kings trace their lineages back to the pre-colonial Islamic kingdoms that ruled the region, making those places especially strong repositories of classical Javanese culture. Classic arts of Java include gamelan music and wayang puppet shows.

Java was the site of many influential kingdoms in the Southeast Asian region,[56] and as a result, many literary works have been written by Javanese authors. These include Ken Arok and Ken Dedes, the story of the orphan who usurped his king, and married the queen of the ancient Javanese kingdom; and translations of Ramayana and Mahabharata. Pramoedya Ananta Toer is a famous contemporary Indonesian author, who has written many stories based on his own experiences of having grown up in Java, and takes many elements from Javanese folklore and historical legends.

Languages spoken in Java (Javanese is shown in white). "Malay" refers to Betawi, the local dialect as one of Malay creole dialect.

The three major languages spoken on Java are Javanese, Sundanese and Madurese. Other languages spoken include Betawi (a Malay dialect local to the Jakarta region), Osing, Banyumasan, and Tenggerese (closely related to Javanese), Baduy and Bantenese (closely related to Sundanese), Kangeanese (closely related to Madurese), and Balinese.[57] The vast majority of the population also speaks Indonesian, often as a second language.

Indian influences came first with Shaivism and Buddhism penetrating deeply into society, blending with indigenous tradition and culture.[59] One conduit for this were the ascetics, called resi, who taught mystical practices. A resi lived surrounded by students, who took care of their master's daily needs. Resi's authorities were merely ceremonial. At the courts, Brahmin clerics and pudjangga (sacred literati) legitimised rulers and linked Hindu cosmology to their political needs.[59] Small Hindu enclaves are scattered throughout Java, but there is a large Hindu population along the eastern coast nearest Bali, especially around the town of Banyuwangi.

The coming of Islam, strengthened the status structure of this traditional religious pattern. More than 90 percent of the people of Java are Muslims, on a broad continuum between abangan (more traditional) and santri (more modernist). Muslim scholars (Kyai) became the new religious elite as Hindu influences receded. Islam recognises no hierarchy of religious leaders nor a formal priesthood, but the Dutch colonial government established an elaborate rank order for mosque and other Islamic preaching schools. In Javanese pesantren (Islamic schools), The Kyai perpetuated the tradition of the resi. Students around him provided his needs, even peasants around the school.[59]

Pre-Islamic Javan traditions have encouraged Islam in a mystical direction. There emerged in Java a loosely structured society of religious leadership, revolving around kyais, possessing various degrees of proficiency in pre-Islamic and Islamic lore, belief and practice.[59] The kyais are the principal intermediaries between the villages masses and the realm of the supernatural. However, this very looseneess of kyai leadership structure has promoted schism. There were often sharp divisions between orthodox kyais, who merely instructed in Islamic law, with those who taught mysticism and those who sought reformed Islam with modern scientific concepts. As a result, there is a division between santri, who believe that they are more orthodox in their Islamic belief and practice, with abangan, who have mixed pre-Islamic animistic and Hindu-Indian concepts with a superficial acceptance of Islamic belief.[59]

There are also Christian communities, mostly in the larger cities, though some rural areas of south-central Java are strongly Roman Catholic. Buddhist communities also exist in the major cities, primarily among the Chinese Indonesian. The Indonesian constitution recognises six official religions.

A wider effect of this division is the number of sects. In the middle of 1956, the Department of Religious Affairs in Yogyakarta reported 63 religious sects in Java other than the official Indonesian religions. Of these, 35 were in Central Java, 22 in West Java and six in East Java.[59] These include Kejawen, Sumarah, Subud, etc. Their total membership is difficult to estimate as many of their adherents identify themselves with one of the official religions.[60] Sunda Wiwitan is a traditional Sundanese religion, its adherents still exist in several villages.[61]
