尉遅迥
Yuwen Tai died in 557, and his nephew Yuwen Hu, serving as the guardian for Yuwen Tai's son Yuwen Jue, forced Emperor Gong of Western Wei to yield the throne to Yuwen Jue in spring 558, ending Western Wei and establishing Northern Zhou, with Yuwen Jue as emperor (but using the alternative title "Heavenly Prince" ("Tian Wang") (as Emperor Xiaomin). Emperor Xiaomin created Yuchi Jiong the Duke of Shu, in commemoration of his victory (as the modern Sichuan region was known in ancient times as the region of Shu). Later in 558, when Emperor Xiaomin tried to seize power from Yuwen Hu, Yuwen Hu deposed and then killed him, making Emperor Xiaomin's older brother Yuwen Yu the Duke of Ningdu emperor instead (as Emperor Ming). Yuchi Jiong's stance in this power struggle is not known, but his brother Yuchi Gang sided with Yuwen Hu.
