Fa Ngum
Fa Ngum again led Lan Xang to war in the 1360s against Sukhothai, in which Lan Xang was victorious in defense of their territory but gave the competing court factions and the war weary population a justification to depose Fa Ngum in favor of his son Oun Huean. Fa Ngum became an exile in Muang Nan, where he died between 1373 and 1390.
