Kingdom of Vientiane
Beginning in 1707 the Lao kingdom of Lan Xang was partitioned into regional kingdoms of Vientiane, Luang Prabang and later Champasak (1713). The Kingdom of Vientiane was the strongest of the three, with Vientiane extending influence across the Khorat Plateau (now part of modern Thailand) and conflicting with the Kingdom of Luang Prabang for control of the Xieng Khouang Plateau (on the border of modern Vietnam).
