Life

In 1246, upon the abdication of Emperor Go-Saga, Go-Fukakusa became Emperor at the age of 2. Go-Saga began to reign as cloistered Emperor.

In 1259, at the insistence of Retired Emperor Go-Saga, he abdicated at the age of 15 to his younger brother, Emperor Kameyama.

After Go-Uda's ascension, Saionji Sanekane negotiated with the Bakufu, and succeeded in getting Go-Fukakusa's son Hirohito named as Crown Prince. In 1287, with the ascension of Emperor Fushimi, Go-Fukakusa's cloistered rule began.

In 1290, he entered the priesthood, retiring from the position of cloistered Emperor. But, with his seventh son, Imperial Prince Hisaaki becoming the 7th Kamakura shōgun among other things, the position of his Jimyōin-tō became strenghtened.

In 1304, he passed away.
