Yuan He

Yuan He (源賀) (403 – October 22, 479), né Tufa Poqiang (禿髮破羌), formally Prince Xuan of Longxi (隴西宣王), was a high-level official of the Chinese/Xianbei dynasty Northern Wei. He was a son of Southern Liang's last prince Tufa Rutan, and after Southern Liang's destruction he fled to Northern Wei and began to serve as an official, gradually reaching positions of great power during the reigns of Emperor Wencheng and Emperor Xianwen.

Tufa Poqiang was born in 403, a year after his father Tufa Rutan had become Southern Liang's prince. After Southern Liang was destroyed by Western Qin in 414, Tufa He appeared to have, along with his father and most of his family, surrendered to Western Qin's prince Qifu Chipan. After his older brother Tufa Hutai (禿髮虎台) and sister Princess Tufa (Qifu Chipan's wife) were executed in 423, after their failed plot to assassinate Qifu Chipan, Tufa Poqiang, along with a number of his brothers and other relatives, first fled to Northern Liang, and then to Northern Wei. He was created the Marquess of Xiping, and Emperor Mingyuan was particularly amazed at his talents. Because the Tufa clan and Emperor Mingyuan's Tuoba clan traced their lines to a common ancestor, Emperor Mingyuan changed Tufa Poquiang's surname to Yuan (源), meaning "origin."

Tufa Poqiang, now named Yuan Poqiang, soon became a Northern Wei general. Because he was able to defeat a number of rebellious tribes, he received repeated promotions.

When Emperor Mingyuan's son Emperor Taiwu made a major attack on Northern Liang in 439, intending to destroy it and annex its territory, Yuan was his guide. Yuan was able to persuade a number of Xianbei tribes, which had been subjects of his grandfather Tufa Sifujian (禿髮思復犍), to submit to the Northern Wei army, greatly helping Northern Wei forces with their food supplies during the successful siege of Northern Liang's capital Guzang (姑臧, in modern Wuwei, Gansu). For his contributions, Yuan's title was upgraded to Duke of Xiping. He appeared to be uninvolved in the subsequent rebellion by his brother Tufa Baozhou (禿髮保周), and he was not punished on account of Tufa Baozhou's rebellion. He followed Emperor Taiwu on campaigns against Rouran and the Xiongnu rebel Gai Wu (蓋吳), and he often was on the frontlines, not fearing for his own safety. Emperor Taiwu warned him against being overly aggressive, and changed his personal name from Poqiang (meaning "defeat the Qiang") to He (meaning "congratulations"), believing the name to fit better.
