Yuan Di, emperor of the Liang dynasty (died 555)

Emperor Yuan of Liang, personal name Xiao Yi (蕭繹), courtesy name Shicheng (世誠), childhood name Qifu (七符), was an emperor of the Chinese Liang dynasty. After his father Emperor Wu and brother Emperor Jianwen were successively taken hostage and controlled by the rebel general Hou Jing, Xiao Yi was largely viewed as the de facto leader of Liang, and after defeating Hou in 552 declared himself emperor. In 554, after offending Yuwen Tai, the paramount general of rival Western Wei, Western Wei forces descended on and captured his capital Jiangling, executing him and instead declaring his nephew Xiao Cha the Emperor of Liang.

The Liang dynasty, alternatively known as the Southern Liang or Xiao Liang in historiography, was an imperial dynasty of China and the third of the four Southern dynasties during the Northern and Southern dynasties period. It was preceded by the Southern Qi dynasty and succeeded by the Chen dynasty. The rump state of Western Liang existed until it was conquered in 587 by the Sui dynasty.
