 Thirteen villages of the Mogok Stone Tract were given to Momeik in 1420 as a reward for helping Yunnan raid Chiang Mai.In 1465, Nang Han Lung, the daughter-in-law of the Saopha ("Sawbwa" in Burmese) of Momeik, sent ruby as separate tribute from Hsenwi and succeeded in keeping the former possessions of Hsenwi until 1484 when Mogok was ceded to the Burmese kings.It was however not until 1597 that the Saopha of Momeik was forced to exchange Mogok and Kyatpyin with Tagaung, and they were formally annexed by royal edict.
