尉遅迥
In summer 580, Northern Zhou's Emperor Xuan died suddenly, and his father-in-law Yang Jian seized power as regent. The generals Yuchi Jiong rose against Yang, and he was joined by the generals Sima Xiaonan (司馬消難) and Wang Qian (王謙). Sima, the governor of Xun Province (勛州, Chen Xiaogan, Hubei) and the nine surrounding provinces, soon surrendered to Chen, seeking Chen aid. Emperor Xuan sent the generals Fan Yi (樊毅), Ren Zhong (任忠), and Chen Huiji (陳慧紀) to attack Northern Zhou's southern provinces to aid Sima, whom he created the Duke of Sui. However, Wei Xiaokuan quickly defeated Yuchi, forcing Yuchi to commit suicide, and Sima's own forces collapsed. He was forced to flee to Chen territory, and all of the territory he controlled was retained by Northern Zhou. Yang Jian soon seized the throne in spring 581, destroying the Northern Zhou and establishing the Sui Dynasty.
