Born in Kyoto as the ninth son of Minamoto no Yoshitomo and known in childhood as Ushiwakamaru. After his father's defeat and death in the Heiji Rebellion of 1159, he was placed in the care of Kuramdera temple and spent his boyhood there. As he grew he sought the protection of the Oshu Fujiwara and honed his martial skills in Hiraizumi (present-day Iwate). When his brother Yoritomo raised his banner in 1180, Yoshitsune rushed to join him and immediately displayed extraordinary military genius. At the Battle of Ichinotani in 1184 he annihilated the Taira forces with a surprise charge down steep cliffs — the famous "Hiyodorigoe no Sakao toshi" — and won again by unconventional tactics at the Battle of Yashima in 1185. At Dan-no-ura later that year Emperor Antoku drowned and the Taira clan was destroyed. However, Yoshitsune had flaunted his exploits and independently accepted court titles from the imperial court against Yoritomo's wishes, causing a rapid deterioration in the brothers' relationship. Driven out of the capital and wandering, he finally sought refuge again with the Oshu Fujiwara. But Fujiwara no Yasuhira, bowing to Yoritomo's pressure, attacked him, and on 15 June 1189 Yoshitsune took his own life at the Koromo River fortress (present-day Hiraizumi, Iwate) at age 30. His tragic life gave birth to the cultural concept of hogan-biiki — sympathy for the underdog — and became the symbol of a distinctly Japanese sensibility of compassion for those of brief glory and unjust fate.
