Jin Shuren
The situation in Xinjiang deteriorated with the assassination of Yang Zengxin in 1928 and the rise to power of his deputy, Jin Shuren (金樹仁), who declared himself governor after arresting and executing Yang's assassin, a rival official named Fan Yaonan (樊耀南) who had planned to assume the position for himself. Autocratic, corrupt, and ineffective at managing the province's development, Jin further antagonized the populace by reinstituting Sinicization policies, increasing taxes, prohibiting participation in the hajj and bringing in Han Chinese officials to replace local leaders.
