Emperor Gaozu of Tang
Zhu Can () (died 621) was an agrarian rebel leader during the disintegration of the Chinese dynasty Sui Dynasty. He was particularly noted for his cruelty and his penchant for favoring cannibalism, and he, while not having a set base of operation, generally roved with his army in the modern southern Henan area, claiming for himself the title of Emperor of Chu. He also at times submitted to Li Mi the Duke of Wei, the Sui emperor Yang Tong, Emperor Gaozu of Tang, and Wang Shichong the Emperor of Zheng. After finally breaking with Tang, he fled to the Zheng capital Luoyang, and after Luoyang fell to Tang in 621, he was executed.
