Hanthawaddy Kingdom

The Hanthawaddy kingdom (Mon: ဍုၚ် ဟံသာဝတဳ, [hɔŋsawətɔe]; Burmese: ဟံသာဝတီ နေပြည်တော်; also Hongsawatoi or simply Pegu), classical name Ham̥sāvatī ("Realm of Hamsa"), was the polity that ruled lower Burma (Myanmar) from 1287 to 1539 and from 1550 to 1552. The Mon-speaking kingdom was founded as Ramaññadesa (Mon: ရးမည, Burmese: ရာမည ဒေသ) by King Wareru following the collapse of the Pagan kingdom in 1287 as a nominal vassal state of the Sukhothai kingdom and of the Mongol Yuan dynasty. The kingdom became formally independent of Sukhothai in 1330 but remained a loose federation of three major regional power centres: the Irrawaddy Delta, Bago, and Mottama. Its kings had little or no authority over the vassals. Mottama was in open rebellion from 1363.
