Life
He became Crown Prince on the eleventh month, twenty-sixth day (or November 26?), and became Emperor on the same day upon the abdication of his father. His father's kampaku, Fujiwara Morozane (藤原師実) became sesshō (regent), but Shirakawa held actual power as cloistered Emperor. Horikawa filled his reign with scholarship, tanka, and music.
When his empress (kōgō) died, his son, Imperial Prince Munehito, who had become Crown Prince (and later became Emperor Toba) was taken to be raised by Horikawa's father, the Retired Emperor Shirakawa.
He passed away at the age of 28, being succeeded by his son, Emperor Toba.
EmperorShirakawa (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 Emperor Sutoku, officially the son of EmperorToba, Shirakawa's grandson.
EmperorHorikawa (堀河天皇 Horikawa Tennō) (August 8, 1079 – August 9, 1107) was the 73rd imperial ruler of Japan, according to the traditional order of succession.

When his empress consort (kōgō) died, his son, Imperial Prince Munehito, who had become Crown Prince (and later became EmperorToba) was taken to be raised by Horikawa's father, the retired EmperorShirakawa.
