Emperor Shirakawa (白河天皇 Shirakawa Tennō) (July 7, 1053 – July 24, 1129) was the 72nd imperial ruler of Japan, according to the traditional order of succession.
He was the first emperor to ostensibly retire to a monastery, but in fact continue to exert considerable influence over his successor.
Note: there's also a theory that Shirakawa was the actual father of EmperorSutoku, officially the son of EmperorToba, Shirakawa's grandson.
Emperor Shirakawa (r.107286) continued to rule as a retired emperor after his abdication, and, after 1096, as a priestly retired emperor.
Sutoku was exiled, and many of his supporters were executed, but this war brought no lasting peace.
Goshirakawa, as retired emperor (115892), had some influence in the government, but in 1167 Kiyomori had himself appointed prime minister and gave important posts in the central and provincial governments to his clansmen.
