The Restored Hanthawaddy Kingdom (Burmese: ဟံသာဝတီ နေပြည်တော်) was the kingdom that ruled Lower Burma and parts of Upper Burma from 1740 to 1757. The kingdom grew out of a rebellion by the Mon people, who then formed the majority in Lower Burma, against the Burman Toungoo Dynasty of Ava in Upper Burma. The rebellion succeeded in restoring the fallen Mon-speaking Kingdom of Hanthawaddy, which ruled Lower Burma from 1287 to 1539. Supported by the French, the upstart kingdom quickly carved out a space for itself in Lower Burma, and continued its push northward. In March 1752, its forces captured Ava, and ended the 266-year-old Toungoo dynasty.
