Emperor Go-Sanjō of Japan (d. 1073)
Emperor Go-Sanjō (後三条天皇, Go-Sanjō-tennō, September 3, 1032 – June 15, 1073) was the 71st emperor of Japan, according to the traditional order of succession.Go-Sanjō's reign spanned the years from 1068 through 1073.This 11th century sovereign was named after Emperor Sanjō and go- (後), translates literally as "later;" and thus, he is sometimes called the "Later Emperor Sanjō", or, in some older sources, may be identified as "Sanjō, the second" or as "Sanjo II."

It was during, and due to, his reign that the Fujiwara grip on power was broken; following Go-Sanjo's rule, their power continued to wane until 1150, where any semblance of their power disappeared.
