Myanmar
By the 9th century, several city-states had sprouted across the land: the Pyu in the central dry zone, Mon along the southern coastline and Arakanese along the western littoral. The balance was upset when the Pyu came under repeated attacks from Nanzhao between the 750s and the 830s. In the mid-to-late 9th century the Bamar people founded a small settlement at Bagan. It was one of several competing city-states until the late 10th century when it grew in authority and grandeur.
