Emperor Sushun

Emperor Sushun (崇峻天皇 Sushun Tennō) was the 32nd emperor of Japan (587-592), according to the traditional order of succession. He was the twelfth son of the Emperor Kimmei by Oane no Kimi, a daughter of Soga no Iname who was the chief of the Soga clan. His name at birth was Prince Hatsusebe (長谷部皇子 Hatsusebe no Miko).

He succeeded his half brother, Emperor Yōmei in 587 with the support of the Soga clan and Empress Suiko, his half sister and the widow of Emperor Bidatsu. The Mononobe clan allied with Prince Anahobe, another son of Kimmei, and attempted to have him installed as emperor, but failed. The head of the Soga clan, Soga no Umako, killed Mononobe no Moriya, the head of the Mononobe clan, which led to its decline.

He was assassinated in 592 after losing the support of the Soga clan.
