Japanese: 城資永 - じょう・すけなが

Year of death: 1181
Year of birth: Year of birth unknown. A military commander in the late Heian period. His name can also be written as Sukenaga. His father was Jokuro Sukekuni. His mother is said in the Azuma Kagami to be the daughter of Kiyohara Takehira, but is unknown. The Jō clan advanced from Dewa Province to Echigo Province in the late 11th century, and was a powerful samurai group that expanded its influence throughout the northern part of Echigo Province throughout the 12th century. Sukenaga was the direct descendant of the clan, and is thought to have had his base in Okuyamasho. In January 1181 (Jishō 5), at Sukenaga's request, an imperial edict was issued to subjugate the Genji clan in the eastern provinces, and he attempted to kill Kiso Yoshinaka in Shinano Province, but died of illness before he could accomplish his goal. In January 1201, Suenaga's younger brother Nagashige raised an army in Kyoto to overthrow the Kamakura shogunate. In response, Suenaga's son Sukemori and his sister Sakanoda rose up in rebellion at Torisakayama in Echigo Province, but were defeated by the shogunate forces, and the Shiro clan was wiped out.

平安後期の武将。名は助永とも書く。父は城九郎資国。母は『吾妻鏡』には清原武衡の娘とする所伝を載せるが,不詳。城氏一族は,11世紀後半に出羽国から越後国に進出し,12世紀を通して,越後国北部域に勢力を拡げた豪族的武士団。資永はその嫡流で,本拠地は奥山荘にあったと考えられている。資永の申請により,治承5(1181)年1月,東国の源氏討伐の院宣が下され,信濃国の木曾義仲を討とうとするが,果たせぬまま病死。正治3(1201)年1月に資永の弟・長茂が鎌倉幕府を打倒するため京都で挙兵したのに呼応して資永の子・資盛や妹・坂額が越後国鳥坂山で蜂起するが幕府軍に敗れ,城氏一族は滅亡した。
