Su Jun

Su Jun (蘇峻) (died 328) was a Jin Dynasty (265–420) general, whose rebellion against Emperor Cheng's regent Yu Liang was initially successful, allowing him to take over the imperial government, but he was eventually defeated by Tao Kan and Wen Jiao's forces and killed in battle. The disturbance he created greatly weakened the Jin regime, which for decades did not have any ability to fight back against rival Later Zhao.

Su Jun's father Su Mo (蘇模) was a prime minister of the Dukedom of Anle—the dukedom that was given to Liu Shan the last emperor of Shu Han and his descendants. Su himself was known for his intelligence when he was young. In the aftermaths of Han Zhao's capture of Emperor Huai, Su gathered a group of refugees on modern Shandong Peninsula and served as the leader of self-protection league. This eventually brought the attention of Cao Ni (曹嶷) -- a general with substantial forces in modern Shandong who frequently changed his allegiance between Han Zhao and Jin, and after Cao could not persuade Su to join him, he became determined to destroy Su. Su became fearful, and in 319 he took his group of refugees south to join the Jin imperial regime under Emperor Yuan, then located at Jiankang. Emperor Yuan was impressed at how Su kept his group of refugees together and how he had come a long distance to join him, and he made Su a commandery governor. He went through a succession of posts the next few years.

In 324, when the warlord Wang Dun's forces attacked Jiankang, with intent to overthrow Emperor Yuan's successor Emperor Ming, Emperor Ming summoned Su, among other generals posted on the northern border with Later Zhao, to come to his aid. When Su's forces (and those of Liu Xia (劉遐)) arrived in the capital late at night, Emperor Ming personally went to visit the forces. Su was instrumental in subsequently defeating Wang's forces, preserving Jin. After this success, Su was made the governor of Liyang Commandery (歷陽, roughly modern Chaohu, Anhui). He became proud of his success and began to have greater ambition, and he received criminals and other unwanted people into his commandery, seeking to strengthen his own personal force.
