Japanese: 安田義定 - やすだ・よしさだ

Year of death: August 19, 1194 (September 5, 1194)
Year of birth: 1134
A military commander from the end of the Heian period to the early Kamakura period. A resident of Kai Province (Yamanashi Prefecture). Son of Kai Genji Minamoto Yoshikiyo and adopted son of his elder brother Kiyomitsu. In 1180 (Jisho 4), he raised an army with his family in response to Minamoto no Yoritomo's uprising. After the victory at the Battle of Fujigawa, he was appointed by Minamoto no Yoritomo as the guardian of Totomi Province (Shizuoka Prefecture), but showed his own independent actions, such as entering Kyoto in response to Minamoto no Yoshinaka's visit to Kyoto (1183) and being appointed as the governor of Totomi by the Imperial Court. He later participated in the defeat of Yoshinaka and the Battle of Ichinotani (1184), but it is thought that he did not become completely subordinate to Yoritomo until after the downfall of the Taira clan. In 1193 (Kenkyu 4), he incurred the wrath of Yoritomo for an affair with his son Yoshisuke, and his territory was confiscated. The following year, he was executed on suspicion of treason.

平安末・鎌倉初期の武将。甲斐国(山梨県)の住人。甲斐源氏源義清の子で兄清光の養子。治承4(1180)年,源頼朝の挙兵に応じて一族と共に挙兵。富士川の戦の勝利後,源頼朝より遠江国(静岡県)の守護に任ぜられたが,源義仲の上洛(1183)に呼応して入京し,朝廷から遠江守に任ぜられるなど,独自の動きをみせる。その後,義仲討滅や一の谷の戦(1184)に参加するが,頼朝に完全に従属するのは平家滅亡後と考えられる。建久4(1193)年,子の義資の縁座で頼朝の勘気を蒙り所領も没収された。さらに翌年,謀反の疑いで誅殺された。
