Emperor Toba

Emperor Toba (1103–1156) was the 74th emperor of Japan. Raised by his grandfather, the cloistered Emperor Shirakawa, he was placed on the throne at four in 1107 and forced to abdicate in 1123 in favour of his son Sutoku, and only took power on Shirakawa's death in 1129.

As cloistered sovereign he dominated the reigns of Sutoku, Konoe and Go-Shirakawa for 28 years. Ordained in 1142, he died in 1156; the ensuing succession feud became the Hōgen Rebellion.
