Yuwen Tai
Yuwen Hu (宇文護) (513 – 14 April 572), courtesy name Sabao (薩保, also a title, which can be traced back to "sartpāw “caravan leader”", but was used as given name, in many cases by Buddhists - referring to the metaphorical meaning of wise leader), formally Duke Dang of Jin (晉蕩公), was a regent of the Xianbei-led Northern Zhou dynasty of China. He first came into prominence as the nephew of Western Wei's paramount general Yuwen Tai, and after Yuwen Tai's death in 556, he became the guardian to Yuwen Tai's son Yuwen Jue. In 557, he forced Emperor Gong of Western Wei to yield the throne to Yuwen Jue (Emperor Xiaomin), establishing Northern Zhou. However, Yuwen Hu dominated the political scene, and after Emperor Xiaomin tried to seize power later that year, he killed Emperor Xiaomin and replaced him with another son of Yuwen Tai, Emperor Ming. In 560, he poisoned Emperor Ming, who was succeeded by another son of Yuwen Tai, Emperor Wu. In 572, Emperor Wu ambushed Yuwen Hu and killed him, personally taking power.
