Emperor Go-Ichijō

Emperor Go-Ichijō (後一条天皇, Go-Ichijō-tennō; October 12, 1008 – May 15, 1036) was the 68th emperor of Japan, according to the traditional order of succession.

Go-Ichijō's reign spanned the years from 1016 through 1036.

This 11th century sovereign was named after his father, Emperor Ichijō, and go- (後), translates literally as "later"; thus, he is sometimes called the "Later Emperor Ichijō", or, in some older sources, may be identified as "Emperor Ichijō, the second", or even "Emperor Ichijō II".
