Emperor Go-Sanjō

Emperor Go-Sanjō (1034–1073), personal name Takahito, was the 71st emperor of Japan. A younger son of Emperor Go-Suzaku by the imperial princess Teishi, he was the first emperor in 170 years whose mother was not a Fujiwara, and the kampaku Fujiwara no Yorimichi cold-shouldered him as crown prince.

Succeeding his half-brother Go-Reizei in 1068, he ruled in person, issuing the Enkyū Shōen Regulation Decree of 1069 to curb Fujiwara wealth. He abdicated in 1073 in favour of his son Shirakawa, took Buddhist vows, and died at 40 before his cloistered rule could begin.
