Kyogoku Mochikiyo

Japanese: 京極持清 - きょうごく・もちきよ

Year of death: Bunmei 2.8.4 (August 30, 1470)
Year of birth: 1407
A military commander in the Muromachi period. His posthumous name was Seikan. He was the third son of Takamitsu. When his father Takamitsu died in August 1413, the family headship passed to his eldest brother Mochitaka (Mochimitsu), but as he was still a child, his uncle Takakazu became his guardian. However, when Mochitaka died of illness in January 1439, Takakazu and then Mochikiyo inherited the family headship as Mochitaka had no legitimate son. This was in December 1441. Mochikiyo's military actions had already been seen in 1441, when he was part of the army that pursued Ashikaga Mochiuji, but as soon as he inherited the family headship, he began to stand out more and more as the governor of the provinces of Omi, Izumo, and Hida. In Kakitsu 1, he was appointed head of the Samurai Department, replacing Yamana Mochitoyo, and in office he served from Kakitsu 1 to Bun'an 4 (1447) and from Hōtoku 1 (1449) to Bunshō 1 (1466), during which time he appointed senior vassal Taga Takatada as shoshidai. When the Onin War began, Mochikiyo joined the Eastern Army (Hosokawa Katsumoto's side) while his direct descendant Rokkaku Takayori joined the Western Army (Yamana Mochitoyo's side), splitting the Sasaki clan in two, but Mochikiyo allied with Takayori's cousin Masataka, and worked to weaken the Western Army's power in Omi and expand the influence of the Kyogoku clan. He can be described as the greatest figure in the Kyogoku clan since Doyō. At the start of the war, the Eastern Army held the upper hand in Omi, but after Mochikiyo's death the situation changed drastically and the Kyogoku clan itself fell into extreme confusion.

没年：文明2.8.4(1470.8.30)
生年：応永14(1407)
室町時代の武将。法名は生観。高光の3男。父高光が応永20(1413)年8月に死去すると,家督は長兄の持高(持光)に譲られたが,幼少であったため叔父高数が後見役となった。しかし永享11(1439)年1月に持高が病死すると,持高には嫡子がなかったため,高数,次いで持清が家督を継ぐこととなった。嘉吉1(1441)年12月のことである。持清はすでに永享10年の足利持氏追討軍の一員として出陣するなど,その軍事行動がみられるが,家督を継ぐや近江,出雲,飛騨の各国守護として,ますます頭角を現すようになった。嘉吉1年には山名持豊に代わって侍所頭人に就任,在位期間は,嘉吉1年～文安4(1447)年,宝徳1(1449)年～文正1(1466)年におよび,この間,所司代に重臣多賀高忠を任命している。応仁の乱が始まると持清は東軍(細川勝元方)に属し,嫡流の六角高頼は西軍(山名持豊方)に属して佐々木一族は二分されたが,持清は高頼の従兄政尭と結び,近江における西軍勢力の弱体化を図り,京極家の勢力拡大に奔走した。京極家において導誉以来の傑物といえる。大乱当初,近江国内は東軍優位で推移したが,持清が死去すると状況は一変し,京極家の内部でも混乱を極めるに至った。
