Emperor Xuan of Northern Zhou (北周宣帝) (559 – 22 June 580^[3]), personal name Yuwen Yun (宇文贇), courtesy name Qianbo (乾伯), was an emperor of the Xianbei-led Northern Zhou dynasty of China.^[4] 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 April 579, less than a year after taking the throne, and subsequently entitled not only his wife Yang Lihua empress, but four additional concubines as empresses. After his death in June 580, the government was taken over by his father-in-law Yang Jian, who soon deposed his son Emperor Jing, ending the Northern Zhou and establishing the Sui dynasty.

However, according to Yang Jian's biography in Book of Sui, Emperor Xuan died on the yiwei day of the same month and year. This corresponds to 8 Jun 580 in the Julian calendar. (大象二年五月...乙未，帝崩。) Sui Shu, vol.01. The Book of Zhou recorded that for the yiwei day of that month, Emperor Xuan merely fell ill and returned to the palace; Bei Shi also had a similar record of Emperor Xuan's death as Zhou Shu.
