Nevertheless, the Xinjiang Governor Jin Shuren (1928–1933), sought to take advantage of the power vacuum left after the death of Shah Mahsut and decreed the abolition of the Kumul Khanate, preventing the new ruler, Shah Mahsut's son Nazir, from assuming control. At the same time, Jin Shuren arranged for Han Chinese migrants from Gansu to settle in the abolished Khanate. These events sparked the Kumul Rebellion in 1931, which was led by Hui warlord Ma Chung-ying in Gansu after his June 1931 meeting with Hoja Niyaz and Yulbars Khan.
