The Hanthawaddy Kingdom (Mon: ဍုၚ် ဟံသာဝတဳ, [hɔŋsawətɔe]listenⓘ; Burmese: ဟံသာဝတီ နေပြည်တော်; also Rone Hongsarwatoi or simply Pegu) was the polity that ruled lower Burma (Myanmar) from 1287 to 1539 and from 1550 to 1552.

[2] 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.

The war ended in a stalemate but was a victory for Hanthawaddy as Ava finally gave up its dream of restoring the Pagan Empire.

After the war, Hanthawaddy entered its golden age, whereas its rival Ava gradually declined.

Its merchants traded with traders from across the Indian Ocean, filling the king's treasury with gold and silver, silk, and spices.
