Phayu
Phayu was king of the Lan Na kingdom in northern Thailand, succeeding his father Khamfu, who by legend died after being bitten by a mermaid or crocodile. A chronicle records that his ministers crowned him at Chiang Mai when he was twenty-eight. Khamfu had moved the court to Chiang Saen; Phayu moved the capital back to Chiang Mai.
Tradition portrays him as a righteous Buddhist ruler, under whom the kingdom knew peace and prosperity and Buddhism flourished. He died in 1355, and the ministers invited his son Kue Na, governor of Chiang Saen, to take the throne.
