Guanqiu Jian
In 255, Guanqiu Jian and Wen Qin started a rebellion in Shouchun (壽春; around present-day Shou County, Anhui) against the Wei regent Sima Shi, who came to power in 251 and monopolised state power, effectively rendering the Wei emperor a puppet ruler. Some historians argue that Guanqiu Jian rebelled because he remained loyal to the Wei emperor, Cao Mao, and was displeased that the Sima family was controlling the Wei government behind the scenes. Other sources state that he was close to Xiahou Xuan, who was purged by Sima Shi in 254 around the time Sima Shi deposed the third Wei emperor Cao Fang and replaced him with Cao Mao; Guanqiu Jian, fearing that he would end up like Xiahou Xuan, decided to rebel against Sima Shi. The rebellion was effectively suppressed within months and Guanqiu Jian was slain by one Zhang Shu () after escaping from Shouchun to Shen County (慎縣; present-day Feidong County, Anhui). Most of Guanqiu Jian's family members were killed while the surviving ones escaped and defected to Wei's rival state, Eastern Wu.
