The Northern Zhou (; Chinese: 北周; pinyin: Bĕi Zhōu) followed the Western Wei, and ruled northern China from 557 to 581 AD. The last of the Northern Dynasties of China's Northern and Southern dynasties period, it was eventually overthrown by the Sui Dynasty. Like the preceding Western and Northern Wei dynasties, the Northern Zhou were members of the Tuoba clan of the Xianbei.
The 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 his death in 580, when he was already nominally retired (Taishang Huang), Xuan's father-in-law Yang Jian took power, and in 581 seized the throne from Emperor Xuan's son Emperor Jing, establishing Sui. The young Emperor Jing and the imperial Yuwen clan, were subsequently slaughtered by Yang Jian.
