Ava Kingdom
Born in 1392, Khayi was a son of King Razathu II of Launggyet Kingdom, located in present-day northern Rakhine State. The small principality was a pawn caught between its larger neighbors of the Ava Kingdom and Hanthawaddy Pegu Kingdom, which were locked in a bitter Forty Years' War. Khayi was only about nine years old in 1401 when his father (r. 1394–1395, 1397–1401), died. In November 1406, his half-brother King Saw Mon III was driven out by Avan troops led by Crown Prince Minye Kyawswa. His brother fled to Bengal but Khayi fled to Pegu (Bago).
