Uragami clan

A local feudal lord whose main residence was Urakami Sho in Isei County, Harima Province (Hyogo Prefecture). As the Akamatsu clan grew as shugo daimyo (military governor) during and after the Nanboku-cho period, the Urakami clan gradually developed politically as their powerful vassal. In 1367 (Shohei 22, Joji 6), Urakami Yukikage was recognized as the deputy shugo of Akamatsu Norisuke, the shugo of Bizen Province (Okayama Prefecture), and the clan continued to hold the position of deputy shugo of the province, with eastern Bizen becoming an important base for the clan. In 1437 (Eikyō 9), Urakami Saburo was recognized as the inspector-magistrate of Harima Province, but he also served as the deputy shugo under Akamatsu Mitsusuke, the shugo who was also the shoshi of the samurai dokoro. After the restoration of the Akamatsu clan as shugo, Uragami Norimune's political status was extremely high, and he provided fundamental support for the control of the domain, and the clan's influence grew exponentially. In 1502 (Bunki 2), Norimune died. His successor, Shishi Muramune, pursued the shugo Akamatsu Yoshimura in 1520 (Eisho 17) and established control over Harima, Bizen, and Mimasaka (Okayama Prefecture), but became involved in political strife at the center and was killed in battle in 1531 (Kyoroku 4). This marked the end of the Uragami clan's growth as a daimyo.

播磨(はりま)国（兵庫県）揖西(いせい)郡浦上庄(しょう)を本貫とする在地領主。南北朝期以降赤松氏が守護大名として成長するに伴い、その有力家臣としてしだいに政治的に発展した。1367年（正平22・貞治6）備前(びぜん)（岡山県）守護赤松則祐(そくゆう)の守護代として浦上行景が認められるのを初見として、同国守護代職を一族で相継ぎ、備前東部は同氏の重要な拠点になった。また1437年（永享9）浦上三郎は播磨国の検断奉行(ぶぎょう)として認められるが、彼は侍所(さむらいどころ)所司でもあった守護赤松満祐(みつすけ)のもとで所司代をも兼ねていた。守護赤松氏再興後の浦上則宗(のりむね)の政治的地位はきわめて高く、その領国支配を根底から支え、一族の権勢は飛躍的に発展した。1502年（文亀2）則宗は死没。その嗣子(しし)村宗は1520年（永正17）守護赤松義村(よしむら)を追い、播磨、備前、美作(みまさか)（岡山県）に支配権を確立したが、中央の政治抗争にかかわり31年（享禄4）戦死。浦上氏の大名権力としての成長はここに終わった。
