Mohnyin Thado captured Sagaing to become the king of Ava, in present-day Myanmar.

Mohnyin Thado was king of Ava from 1426 to 1439. He is also known in Burmese history as Mohnyin Min Taya after his longtime tenure as the sawbwa of Mohnyin, a Shan-speaking frontier state. He founded the royal house of Mohnyin that would rule the kingdom until 1527.

Sagaing is a town in the Sagaing Region of Myanmar. It is located on the Irrawaddy River, 20 km (12 mi) to the south-west of Mandalay on the opposite bank of the river. Sagaing, with its numerous Buddhist monasteries, is an important religious and monastic centre. The pagodas and monasteries crowd the numerous hills along the ridge running parallel to the river. The central pagoda, Soon U Ponya Shin Pagoda, is connected by a set of covered staircases that run up the 240 m (790 ft) hill.

The Ava Kingdom also known as Inwa Kingdom or Kingdom of Ava was the dominant kingdom that ruled upper Burma (Myanmar) from 1365 to 1555. Founded in 1365, the kingdom was the successor state to the petty kingdoms of Myinsaing, Pinya and Sagaing that had ruled central Burma since the collapse of the Pagan Kingdom in the late 13th century.
