Qi, known in historiography as the Southern Qi ( or ) or Xiao Qi (), was a Chinese imperial dynasty and the second of the four Southern dynasties during the Northern and Southern dynasties era. It followed the Liu Song dynasty and was succeeded by the Liang dynasty. The main polity to its north were the Northern Wei.
History
The dynasty began in 479, when Xiao Daocheng forced the Emperor Shun of Liu Song (宋顺帝) into yielding the throne to him, ending Liu Song and starting Southern Qi, as its Emperor Gao. The dynasty's name was taken from Xiao's fief, which roughly occupied the same territory as the Warring States era Kingdom of Qi. The Book of the Qi does not mention whether or not Xiao had any blood relationship to either the House of Jiang or House of Tian, the two dynasties which had previously ruled that kingdom.
During its 23-year history, the dynasty was largely filled with instability, as after the death of the capable Emperor Gao and Emperor Wu, Emperor Wu's grandson Xiao Zhaoye (萧昭业) was assassinated by Emperor Wu's intelligent but cruel and suspicious cousin Xiao Luan (萧鸾), who took over as Emperor Ming, and proceeded to carry out massive executions of Emperor Gao's and Emperor Wu's sons, as well as officials whom he suspected of plotting against him.川本『中国の歴史、中華の崩壊と拡大、魏晋南北朝』、P152
