In short, the Minamoto won after a hard-fought war and with the continual support of Go-Shirakawa, who had been in contact with Minamoto no Yoritomo since Kiyomori's death in 1181. In 1183 the army of Minamoto no Yoshinaka entered the capital, allowing for Go-Shirakawa's re-entry into the city - he had made a pilgrimage to various shrines, accompanied by armed monks, in order to avoid capture by the Taira. Go-Shirakawa then issued a mandate for Yoshinaka to join with Minamoto no Yukiie in "destroying Munemori and his army", as well as the entire Taira clan. The emperor bestowed upon Yoshinaka the title of "Asahi Shōgun" (旭 将軍). Go-Shirakawa also contributed to the Taira's defeat by attempting to persuade them to lower their guard; in 1184 he promised that if the Taira returned the Imperial Regalia and the emperor he would facilitate a truce with the Minamoto. This meant that they were unprepared for the rapid attack of Minamoto no Noriyori and Minamoto no Yoshitsune at the Battle of Ichi-no-Tani, a decisive battle in the war. Throughout the entire war there were disagreements and struggles for power within the Minamoto clan, which was barely held together by Minamoto no Yoritomo. When Yoritomo secured the support of Go-Shirakawa in this power struggle, Yoshinaka seized the cloistered emperor and burned his palace. After continued internal struggles within the Minamoto clan and fighting with the Taira, Yoshitsune finally destroyed the Taira clan entirely in 1185 at the naval Battle of Dan-no-ura. Although Yoritomo and Go-Shirakawa disagreed in the late 1180s, again related to internal Minamoto issues, after the death of Yoshitsune, Go-Shirakawa and Yoritomo reconciled. Go-Shirakawa allowed Yoritomo to form a shogunate - the imperial authority and validation was required to attain the position of Shogun. In 1192 ("Kenkyū 3, 13th day of the 3rd month") Go-Shirakawa died at the age of 66. He had been father to two emperors — Nijō, the 78th emperor; Takakura, the 80th emperor and grandfather to three emperors— Rokujō, the 79th emperor; Antoku, the 81st emperor; and Go-Toba, the 82nd emperor.
