Year of birth: Gentoku 3/Genko 1 (1331)
A military commander during the Northern and Southern Courts period. Yoshisada's second son. Junior Fifth Rank, Sakonoe no Takumi. It is said that in 1337, when Kitabatake Akiie went to Kyoto to defeat Ashikaga Takauji and his allies, he joined the army and made a great contribution. After his father Yoshisada was killed in battle, he remained in the eastern provinces and played an active role on the side of the Southern Court. During the Kan'o Disturbance in 1352, he allied with Uesugi Noriaki, who supported Ashikaga Naoyoshi, and, accompanying Prince Muneyoshi, raised an army in Kozuke Province (Gunma Prefecture). He defeated the army of the deputy governor of the Utsunomiya clan, the guardian of Kozuke Province, and advanced to Musashi, then proceeded further to occupy Kamakura, and drove the Kamakura kubo Ashikaga Motouji from Kamakura. He fought fierce battles in various places in Musashi with Takauji's army, which had come east from Kinai in preparation for the decisive battle with Naoyoshi, but was defeated without any advantage and fled to Echigo. Afterwards, he carried out disruptive activities in various parts of the eastern provinces, throwing the Kamakura army into confusion. As a result, Hatakeyama Kunikiyo, the steward of the Kamakura province and governor of Musashi Province, was intent on defeating Yoshioki, and is said to have resorted to a scheme to kill him. According to the "Taiheiki," Kunikiyo ordered Takezawa Ukyo-no-jo to approach Yoshioki, and in collusion with Edo Totomi-no-kami, he assassinated him at Yaguchi Ferry on the Tama River. With Yoshioki's death, the Southern Court forces in the eastern provinces were wiped out. <References> "Fundamental Historical Materials on Nitta Yoshisada," compiled by Gunma Prefectural Education Association

南北朝時代の武将。義貞の次男。従五位下,左近衛佐。建武4/延元2(1337)年北畠顕家が足利尊氏らを討つために上洛の折,その軍勢に加わり,功をあげたと伝えられる。父義貞が討死したのちも東国にあり,そこで南朝方として活躍する。観応の擾乱の折,文和1/正平7(1352)年に足利直義派の上杉憲顕と結んで,宗良親王を奉じて上野国(群馬県)で兵をあげた。上野守護宇都宮氏の守護代らの軍勢を破り,武蔵に進み,さらに進んで鎌倉を占拠して,鎌倉公方足利基氏を鎌倉から追った。直義との決戦のため,畿内から東下してきた尊氏軍と武蔵の各所で激戦を展開したが,利なく敗れて越後に逃れた。その後,東国各地で攪乱工作を展開して,鎌倉府軍を混乱させた。そのため鎌倉府執事で武蔵国守護であった畠山国清は義興討伐に腐心し,謀略を用いて殺害したと伝えられる。『太平記』によれば,国清は竹沢右京亮に命じて義興に近付かせ,江戸遠江守と共謀して,多摩川の矢口の渡しで謀殺したという。義興の死により東国の南朝方は一掃された。<参考文献>群馬県教育会編『新田義貞公根本史料』
