Emperor Go-Suzaku

Emperor Go-Suzaku (1009–1045), personal name Atsunaga, was the 69th emperor of Japan and a younger son of Emperor Ichijō and Fujiwara no Shōshi. Named crown prince in 1017 after Prince Atsuakira stepped aside, he succeeded his brother Go-Ichijō in 1036 and ruled for nine years while Fujiwara no Yorimichi dominated the court as regent.

His eldest son, born of Michinaga's daughter Yoshiko, succeeded him as Emperor Go-Reizei; another son, born of the imperial princess Teishi, later became Emperor Go-Sanjō. He abdicated in 1045, took Buddhist vows, and died two days later at 37.
