The Burmese kingdom of Ava had fought wars of unification from 1385 to 1424) but had never quite reassembled its lost empire.

The Mon kingdom of Hanthawaddy, having held off Ava, had entered its golden age, and Arakan had gone on to become a power in its own right.

In contrast, constant warfare had left Ava greatly weakened, and it has slowly disintegrated from 1481 onward.

The Shans of Mohnyin, invading Ava, which has failed to either appease the Shans or gain support from the Burmese kingdom of Toungoo to the south, have by 1524 seized Ava’s border garrisons and gained control of the upper Irrawaddy River, on the left bank of which, at the Myitnge confluence, lies Ava.
