Setthathirat ( 1534-1572 ) and Pha That Luang

Setthathirath (Lao: ເສດຖາທິຣາດ; 1534–1572) is considered one of the great leaders in Lao history. Throughout 1560s until his death, he successfully defended his kingdom of Lan Xang against military campaigns of Burmese conqueror Bayinnaung, who had already subdued Xieng Mai (Chiang Mai) in 1558 and Ayutthaya in 1564. Setthathirath was a prolific builder and erected many Buddhist monuments including Wat Xieng Thong in Louang Phrabang and the That Luang in Vientiane.
