was a Japanese samurai commander of the Minamoto clan of Japan in the late Heian and early Kamakura periods. His older half-brother was Minamoto no Yoritomo, the first shogun of the Kamakura shogunate. His common name was Kurō (; ), and his formal name was Yoshitsune. Born as the ninth son of Minamoto no Yoshitomo of the Kawachi Genji clan, his childhood name was Ushiwakamaru. Due to his father's defeat and death in the Heiji Rebellion, he was entrusted to Kurama-dera temple.
He later traveled down to Hiraizumi, where he received the protection of Fujiwara no Hidehira, the head of the Ōshū Fujiwara clan. When his half-brother Yoritomo raised an army to overthrow the Taira clan (the Jishō-Juei War), Yoshitsune rushed to join him. He became the greatest contributor to the Minamoto victory, destroying the Taira clan through the battles of Ichi-no-Tani, Yashima, and Dan-no-ura.
Although Yoritomo and Yoshitsune initially had a close relationship, described as being like "father and son," Yoshitsune incurred Yoritomo's wrath by accepting court titles without permission and acting independently during the war against the Taira. When Yoshitsune showed signs of seeking his own independence in response, he came into conflict with Yoritomo and was declared an enemy of the court. After an order for his capture was issued nationwide, he fled and once again sought refuge with Fujiwara no Hidehira.
However, after Hidehira's death, Hidehira's successor, Fujiwara no Yasuhira, under pressure from Yoritomo, attacked Yoshitsune.
