Quick Summary

The Kingdom of Champasak was one of three historical kingdoms of Laos, established in 1713. It encompassed lands on both sides of the Mekong River and included the significant Vat Phou ruins, which were once a provincial center for the Cambodian Kingdom of Angkor.1

Over time, the kingdom's territory changed hands. In the 19th century, the western portion was absorbed by Siam (now Thailand). Subsequent Franco-Siamese treaties in the early 20th century reunited the area with the Laotian territory of Champasak. Thailand briefly controlled the land west of the Mekong again between 1941 and 1945. In 1946, Prince Boun Oum of Champasak renounced sovereign rights, leading to the region's incorporation into a united kingdom with its capital at Luang Prabang.1
