Myinsaing Kingdom
The Myinsaing Kingdom also known as Myainsaing Regency was the regency that ruled central Burma from 1297 to 1313. It was founded by three brothers—Athinkhaya, Yazathingyan and Thihathu from Myinsaing— and was one of many small kingdoms that emerged following the collapse of the Pagan Empire in 1287. Myinsaing successfully fended off the second Mongol invasion in 1300–1301, and went on to unify central Burma from Tagaung in the north to Prome (Pyay) in the south. The brothers' co-rule ended between 1310 and 1313, with the death of the two elder brothers Athinkhaya and Yazathingyan.
