Emperor Jianwen of Liang, emperor of the Chinese Liang dynasty (died 551)

Emperor Jianwen of Liang, personal name Xiao Gang (蕭綱), courtesy name Shizuan (世纘), childhood name Liutong (六通), was an emperor of the Chinese Liang Dynasty. He was initially not the crown prince of his father Emperor Wu, the founder of the dynasty, but became the crown prince in August 531 after his older brother Xiao Tong died. In 549, the rebellious general Hou Jing captured the capital Jiankang, and Hou subsequently held both Emperor Wu and Crown Prince Gang under his power, having Crown Prince Gang take the throne after Emperor Wu's death later that year. During Emperor Jianwen's reign, he was almost completely under Hou's control, and in 551, Hou, planning to take the throne himself, first forced Emperor Jianwen to yield the throne to his grandnephew Xiao Dong the Prince of Yuzhang, and then sent messengers to suffocate the former emperor.

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.
