Nanbu clan

A group of warriors established in the early days of the Kamakura Shogunate. Their ancestor was Mitsuyuki, the third son of Kagami Tomitsu of the Seiwa Genji clan, and their family name was from Nanbu-go, Kai Province (Nanbu-cho, Yamanashi Prefecture). As eastern vassals, they acquired territories in various provinces, including Mutsu and Tajima, and at the end of the Kamakura period, they also became vassals of the Hojo clan. Moroyuki was selected by the Mutsu provincial government under the Kenmu administration as the magistrate of northern Oshu, and established the foundation of the Oshu Nanbu clan in Hachinohe-nejo, Nukanobu County (Hachinohe City, Aomori Prefecture). During the Muromachi and Sengoku periods, the Sannohe Nanbu clan took the lead and expanded its influence throughout northern Ouu, competing fiercely with the Akita, Asari, and Onodera clans. During Toyotomi Hideyoshi's Oshu Punishment, Nobunao was granted the fief of seven counties, including Nukabe, Iwate, Kazuno, Shiba, Hei, Hienuki, and Waga, and he put down the rebellion of Kunohe Masazane. He then joined the Tokugawa clan and became the founder of the Morioka Domain.

鎌倉幕府草創期に成立した武士団。清和源氏(せいわげんじ)加賀美遠光(かがみとおみつ)の第3子光行(みつゆき)を祖とし、甲斐国(かいのくに)南部郷（山梨県南部町）を名字(みょうじ)の地とする。東国御家人(ごけにん)として陸奥(むつ)、但馬(たじま)など各国に所領を獲得し、鎌倉末期には北条氏被官ともなる。建武(けんむ)政権下の陸奥国府から師行(もろゆき)が北奥羽の奉行(ぶぎょう)に抜擢(ばってき)されて、糠部(ぬかのぶ)郡八戸根城(はちのへねじょう)（青森県八戸市）に拠(よ)り、奥州南部氏の基盤を確立した。室町・戦国時代には、三戸(さんのへ)南部氏が中心となって、北奥羽全域に勢力を広げ、秋田、浅利、小野寺各勢力と鎬(しのぎ)を削った。豊臣秀吉(とよとみひでよし)の奥州仕置の際、信直(のぶなお)は糠部、岩手、鹿角(かづの)、紫波(しば)、閉伊(へい)、稗貫(ひえぬき)、和賀(わが)7郡の知行(ちぎょう)を安堵(あんど)され、九戸政実(くのへまさざね)の乱を鎮め、さらに徳川家に属して、盛岡藩祖となった。
