Ava Kingdom
Razadarit (, , or ; ; 1368–1421), also known as Rajadhiraj the Great was a notable Mon king of Hanthawaddy Pegu from 1384 to 1421. He successfully unified all of the Mon-speaking areas of modern day Lower Myanmar, 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.
