Liu Weichen

Liu Weichen (劉衞辰) was a chieftain of the Tiefu tribe during the Sixteen Kingdoms period. During the early years of his chieftaincy, Liu Weichen waivered his allegiance between the Di-led Former Qin dynasty and the Tuoba-Xianbei kingdom of Dai. In 376, he guided the Qin in their conquest of Dai, but after the campaign, he rebelled and was defeated by his cousin tribe, the Dugu. He returned to prominence in the Hetao region during the collapse of the Former Qin after the Battle of Fei River, but in 392, he and his tribe were destroyed by the Northern Wei. He was survived by his son, Liu Bobo, who later founded the Helian Xia dynasty and posthumously named him as Emperor Huan of (Helian) Xia (桓皇帝).
