Emperor Wu of Northern Zhou ((北)周武帝) (543–578), personal name Yuwen Yong (宇文邕), nickname Miluotu (禰羅突), was an emperor of the Xianbei dynasty Northern Zhou. As was the case of the reigns of his brothers Emperor Xiaomin and Emperor Ming, the early part of his reign was dominated by his cousin Yuwen Hu, but in 572 he ambushed Yuwen Hu and seized power personally. He thereafter ruled ably and built up the power of his military, destroying rival Northern Qi in 577 and annexing its territory. His death the next year, however, ended his ambitions of uniting China, and under the reign of his erratic son Emperor Xuan (Yuwen Yun), Northern Zhou itself soon deteriorated and was usurped by Yang Jian in 581.
Yuwen Yong was born in 543, as the fourth son of the Western Wei paramount general Yuwen Tai. His mother was Yuwen Tai's concubine Lady Chinu. He was born at Yuwen Tai's then-headquarters at Tong Province (同州, roughly modern Weinan, Shaanxi). He was considered filially pious, respectful, and intelligent in his youth. In 554, Emperor Fei of Western Wei created him the Duke of Fucheng.
The Northern Zhou (Chinese: 北周; pinyin: Bĕi Zhōu) followed the Western Wei, and ruled northern China from 557 to 581. It was overthrown by the Sui Dynasty.
Northern Zhou's basis of power was established by Yuwen Tai, who was paramount general of Western Wei, following the split of Northern Wei into Western Wei and Eastern Wei in 535. After Yuwen Tai's death in 556, Yuwen Tai's nephew Yuwen Hu forced Emperor Gong of Western Wei to yield the throne to Yuwen Tai's son Yuwen Jue (Emperor Xiaomin), establishing Northern Zhou. The reigns of the first three emperors (Yuwen Tai's sons) -- Emperor Xiaomin, Emperor Ming, and Emperor Wu were dominated by Yuwen Hu, until Emperor Wu ambushed and killed Yuwen Hu in 572 and assumed power personally. With Emperor Wu as a capable ruler, Northern Zhou destroyed rival Northern Qi in 577, taking over Northern Qi's territory. However, Emperor Wu's death in 578 doomed the state, as his son Emperor Xuan was an arbitrary and violent ruler whose unorthodox behavior greatly weakened the state. After Emperor Xuan's death in 580 (when he was already titularly retired emperor (Taishang Huang), Emperor Xuan's father-in-law Yang Jian seized power, and in 581 seized the throne from Emperor Xuan's son Emperor Jing, establishing Sui. The imperial Yuwen clan, including the young Emperor Jing, was subsequently slaughtered by Yang Jian.
Emperor Wu or the Wu Emperor (武帝, lit. "The Martial Emperor") is the posthumous name of numerous Chinese rulers:
