Hkun Law (Burmese: ???????, [k??`? l?ยด]; also spelled Khun Law; also Binnya Khon-Law; 1254โ1311) was king of Martaban from 1307 to 1311.
He succeeded the throne after the death of his brother Wareru, who left no male heir.
Though Law gained the recognition of Martaban's overlord Sukhothai, he could not establish any control beyond the capital Martaban (Mottama).
He was powerless to defend the Sittaung valley from raids by the Lan Na kingdom.
His nominal vassals ruled like sovereigns.
In 1311, he was assassinated by the troops of his brother-in-law Gov.
Min Bala of Myaungmya, who placed his son (and Law's nephew) Saw O on the throne.
Most of the monarchs of the Wareru dynasty that ruled the Mon-speaking Lower Burma until the mid-16th century were descended from Law.
