Razadarit (Mon: ရာဇာဓိရာတ်, Burmese: ရာဇာဓိရာဇ်, Burmese pronunciation: [jàzàdəɹɪ̀ʔ] or [jàza̰dəɹɪ̀ʔ]; also spelled Yazadarit; 1368–1421), was king of Hanthawaddy Pegu from 1384 to 1421. He successfully unified his Mon-speaking kingdom, and fended off major assaults by the Burmese-speaking Ava Kingdom (Inwa) in the Forty Years' War. The king also instituted an administrative system that left his successors with a far more integrated kingdom. He is one of the most famous kings in Burmese history.
