Dugu Xin
Dugu Xin, Xianbei name Qimitou, known as Dugu Ruyuan 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, he captured the former Northern Wei capital Luoyang from Eastern Wei in 537. He became one of the Eight Pillars of the State in 548. When the Northern Zhou replaced Western Wei, Dugu Xin was created Duke of Wei, but was soon forced to commit suicide by the powerful regent Yuwen Hu. He received the posthumous name Li.
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, and maternal grandfather to two emperors from two dynasties, all after his death. In fact, every Chinese emperor for 3 centuries was descended from him. During the Sui dynasty, Dugu Xin was honored as Duke Jing of Zhao by Emperor Wen. In 583, Empress Wenxian 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.
