Flag of the Kingdom of Vientiane (1707–1828)

Kingdom of Vientiane was formed in 1707 as a result of the succession dispute between Sai Ong Hue with his backing from the Vietnamese court at Huế and Kingkitsarat (a grandson of Souligna Vongsa) who was backed by the Tai Lü kingdom of Sipsong Panna. From 1707 until the annihilation of Vientiane in 1828, the kingdom would at various times be in rivalry with the kingdoms of Luang Prabang and Champasak, although they remained loosely confederated by cultural and historic affinity. By the mid-eighteenth century, the individual Lao kingdoms were simultaneously paying tribute to Burma, China, Siam and Vietnam. Following the Rebellion of Chao Anouvong in 1828, Vientiane was destroyed and both the kingdoms of Vientiane and Champasak falls to the Siamese in 1828. The kingship of Vientiane ends and all territories are annexed to Siam.[30] General Ratchasuphawadi oversees the depopulation of the kingdom and forced relocation to Isaan. The city itself was leveled leaving only Wat Si Saket standing, along with the partial ruins of the Ha Pra Keo, That Dam Stupa, and That Luang Stupa. In 1867, Louis de Carne a part of the Francis Garnier exploratory mission noted that:

“A flourishing capital has been annihilated in our own days, and an entire people has, in some sort, disappeared, without Europe even having suspected such scenes of desolation-without even a solitary echo of this long cry of despair having reached her.”[31]

Flag of the Kingdom of Champasak (1713–1904)

The Kingdom of Champasak declared itself independent from the Kingdom of Vientiane in 1713. The Kingdom of Champasak comprised the area south of the Xe Bang River as far as Stung Treng together with the areas of the lower Mun and Xi rivers on the Khorat Plateau (now the Isaan area of modern Thailand). The Kingdom was annexed by Siam in 1829 following the Chao Anouvong Rebellion, and subsequent kings were confirmed in Bangkok. From 1893 French took administrative control over parts of the kingdom, in 1904 the kingdom was reduced to a provincial governorship but still included the political involvement of the Na Champasak royal family. From 1941 to 1945 Thailand exploited France's weakness during World War II to acquire Champasak and other Lao lands on the right bank of the Mekong. In 1946 Champasak was ceded back to France and Chao Boun Oum remitted all claims to an independent kingship in order to unify Laos. The Kingdom of Laos (1946–75) was then formed under the Luang Prabang line of kingship.

The early part of his reign saw a considerable increase in population and agricultural production, enabling him to create ten new muang. However, the Siamese slowly increased their presence, appointing their own commissioners to oversea governance in 1884, placing the state under the control of a regional Governor-General in 1891. 38% of revenues were sent directly to the treasury in Bangkok, 59% spent on regional Siamese administrators, and just 3% left to the local administration.

With the division of Lan Xang, the city of Luang Prabang recovered its prestige as a royal city, since the capital had moved to Vientiane with Setthathirath in 1560. The city was a growing center for religion and trade, but remained politically weak and would be sacked by the Burmese in 1764. Throughout the 18th and 19th centuries the Kingdom endured as a vassal to China, Siam, Burma, and Vietnam. In 1828 following Chao Anouvong's Rebellion the kingdom was annexed by Siam. Despite their vassal status the Kings of Luang Prabang exercised a degree of autonomy, but lacked the security apparatus to effectively defend the kingdom (which may have been used in rebellion, as had been done in the kingdoms of Vientiane and Champasak). As a result, throughout the mid-19th century Haw pirates from China were able to invade.

The Muang of Xiang Khouang was a semi-autonomous region in Laos in what is now Xiang Khouang province. The Phuan (Pu’on) monarchy claims descent from Khun Borom and were part of the Lan Xang mandala. Geographic isolation and frequent warfare produced periods where the Phuan kings tried to assert more authority, but the region remained only a key vassalage for surrounding kingdoms. The region features prominently in the 18th and 19th century as valuable coalition piece for the rival kingdoms of Vientiane and Champasak. Xiang Khouang was a trade frontier, and also a frequent point of invasion, and so has more cultural influences from China and Vietnam.

Kings

Flag of the Kingdom of Laos (1952–1975)

The Kingdom of Laos created in 1947 marked the first time the kingdoms of Laos had been unified since the division of Lan Xang in 1707. The Franco-Lao Treaty of 1953, gave Laos independence and the Royal Lao Government took control of the country. This treaty established a constitutional monarchy, with Sisavang Vong as King and Prince Souvanna Phouma as Prime Minister. In 1959, after the death of his father King Sisavang Vong, Sisavang Vatthana ascended the throne and was crowned King. On 2 December 1975, King Sisavang Vatthana was forced to abdicate by the Pathet Lao, after its victory in the Laotian Civil War.
