 Yuwen Tai

Yuwen Tai () (507–556), nickname Heita (黑獺), formally Duke Wen of Anding (安定文公), later further posthumously honored by Northern Zhou initially as Prince Wen (文王) then as Emperor Wen (文皇帝) with the temple name Taizu (太祖), was the paramount general of the Chinese/Xianbei state Western Wei, a branch successor state of Northern Wei.In 534, Emperor Xiaowu of Northern Wei, seeking to assert power independent of the paramount general Gao Huan, fled to Yuwen's domain, and when Gao subsequently proclaimed Emperor Xiaojing of Eastern Wei emperor, a split of Northern Wei was effected, and when Yuwen subsequently poisoned Emperor Xiaowu to death around the new year 535 and declared his cousin Yuan Baoju emperor (as Emperor Wen), the split was formalized, with the part under Gao's and Emperor Xiaojing's control known as Eastern Wei and the part under Yuwen's and Emperor Wen's control known as Western Wei.
