Emperor Xuan of Northern Zhou

Who was Emperor Xuan of Northern Zhou?

Emperor Xuan of Northern Zhou, personal name Yuwen Yun, courtesy name Qianbo, was an emperor of the Mongolian Xianbei dynasty Northern Zhou. He was known in history as an erratic and wasteful ruler, whose actions greatly weakened the Northern Zhou regime. As part of that erratic behavior, he passed the throne to his son Emperor Jing in 579, less than a year after taking the throne, and subsequently entitled not only his wife Empress Yang Lihua empress, but four additional concubines as empresses. After his death in 580, the government was taken over by his father-in-law Yang Jian, who soon deposed his son Emperor Jing, ending Northern Zhou and establishing Sui Dynasty.
