# Dugu Xin

Dugu Xin (Chinese: 獨孤信; 503 – 24 April 557), Xianbei name Qimitou (期彌頭), known as Dugu Ruyuan (獨孤如願) before 540, was a general and official during the chaotic Northern and Southern dynasties period of imperial China. In 534, Dugu Xin followed Emperor Xiaowu of Northern Wei to the west to join the warlord Yuwen Tai, and in the ensuing years led Western Wei forces against their nemesis, the Eastern Wei. Despite an early debacle (after which he fled to and stayed for three years in the southern Liang dynasty before returning to the northwest), he captured the former Northern Wei capital Luoyang from Eastern Wei in 537. He rose to high ranks under Yuwen Tai, and his eldest daughter married Yuwen Tai's son Yuwen Yu. When the Northern Zhou dynasty replaced Western Wei, Dugu Xin was created Duke of Wei (衛國公), but was soon forced to commit suicide by the powerful regent Yuwen Hu. He received the posthumous name Li (戾).
He is best remembered today due to his three daughters: it is because of their marriages that he was a father-in-law to two emperors from two Chinese dynasties (Emperor Ming of Northern Zhou and Emperor Wen of Sui), and maternal grandfather to two emperors from two dynasties (Emperor Yang of Sui and Emperor Gaozu of Tang), all after his death. In fact, every Chinese emperor for 3 centuries (from 604 to 907, with the exception of Wu Zetian and self-proclaimed rebels) was descended from him. During the Sui dynasty, Dugu Xin was honored as Duke Jing of Zhao (趙國景公) by Emperor Wen (who married his seventh daughter Dugu Qieluo). In 583, the Empress built a temple dedicated to his memory in the capital Daxing, the remains of which were discovered in 1997 on the campus of Xi'an Jiaotong University. During the Tang dynasty, he was honored as Prince of Liang (梁王).
