This town was formerly the residence of the Sawbwa of Mongpan State. The four districts of Möng Tang, Möng Hang, Möng Kyawt and Möng Hta, located to the south on the eastbank of the Salween belonged to the Cis-Salween Sawbwa of Möngpan. In 1888 there was trouble owing to the action of Siam, who attempted to take possession of them. Siamesetroops were posted in the four districts. Siam also claimed a further district, Möng Hsat, but posted no troops there.
