The Ispah rebellion (Chinese: 亦思巴奚兵亂; pinyin: Yìsībāxī Bīngluàn) were a series of civil wars in the middle of 14th century in Fujian during the Yuan dynasty. The term Ispah might derive from the Persian word "سپاه" (sepâh), meaning "army" or "Sepoy". Thus, the rebellion is also known as the Persian Sepoy rebellion (波斯戍兵之亂; Bōsī Shùbīng zhī Luàn) in Chinese documents. In 1362, the Ispah army collapsed into internal conflict. In 1366, it was eventually crushed by the ethnic Han commander Chen Youding (陈友定) who was loyal to the Yuan dynasty.
