Razadarit at his accession controlled only the Pegu province out of three principal Mon regions in lower Burma.

The Martaban region is ruled by Byattaba, and the Irrawaddy delta is under the rule of Laukpya of Myaungmya.

Razadarit had pardoned his aunt Mahadevi and given her Dagon in fief but he cannot buy the loyalty of his uncle Laukpya.

Laukpya, who had always ruled his fief like a king under his brother Binnya U, was not prepared to submit to his teenage nephew.

As Razadarit prepared to march to the delta in 1385, Laukpya had sought assistance from King Swa Saw Ke of Ava with the promise of submission to the rival Upper Burmese kingdom in exchange for Razadarit’s overthrow.

This had triggered civil war in Lower Burma; simultaneously, Shans in the north raid into Ava, and Burmese from Prome (Pye) stage a guerilla assault on the Mons.

Razdarit and his Mon forces, after ousting the Burmese from the fort of Myaungmya in the Irrawaddy delta area in 1391, unsuccessfully seeks an armistice with Ava. swa
