After the defeat of the Heike, Minamoto no Yoshitsune fell out with his brother Yoritomo and took refuge with Fujiwara no Hidehira in Hiraizumi. Upon Hidehira's death in 1187, Yoritomo pressured Hidehira's successor, Fujiwara no Yasuhira, through the Imperial Court to surrender Yoshitsune, overriding Hidehira's dying wish to protect him.
On June 15, 1189, Yasuhira led 500 soldiers to attack Yoshitsune at the Koromogawa no tachi residence. Yoshitsune's loyal retainer Benkei fought in defense of his lord and is said to have died standing upright, striking fear into the attackers. Yoshitsune, cornered and defeated, took his own life by seppuku.
The death of Yoshitsune eliminated the last significant rival to Minamoto no Yoritomo within the Minamoto clan. Yoritomo subsequently used the Northern Fujiwara's harboring of Yoshitsune as a pretext to invade and destroy the Northern Fujiwara domain, further cementing the Kamakura shogunate's authority over Japan.
