Kingdom of Vientiane
The Lao rebellion, also known as Anouvong's Rebellion or Lao–Siamese War, was an attempt by King Anouvong (Xaiya Sethathirath V) of the Kingdom of Vientiane to end the suzerainty of Siam and recreate the former kingdom of Lan Xang. In January 1827 the Lao armies of the kingdoms of Vientiane and Champasak moved south and west across the Khorat Plateau, advancing as far as Saraburi. The Siamese quickly mounted a counterattack, forcing the Lao forces to retreat. The Siamese continued north to defeat Anouvong's army. His rebellion had failed, which led to his capture, the destruction of his city of Vientiane in retaliation, a massive resettlement of Lao people to the west bank of the Mekong River, and direct Siamese administration of the former territories of the Kingdom of Vientiane. The legacy of the Lao rebellion is controversial. It is viewed in Thailand as a ruthless and daring rebellion that had to be suppressed, and has given rise to the folk heroes such as Thao Suranari. In Laos, King Anouvong is now revered as a national hero who died in pursuit of complete independence, even though he both lost his life in an ill-advised revolt against heavy odds and virtually guaranteed that the Lao-speaking provinces across the Mekong River would remain as part of Siam (now Thailand).
