The was a Japanese samurai clan active from the late Heian period until the late 16th century. The clan was historically based in Kai Province in present-day Yamanashi Prefecture. The clan reached its greatest influence under the rule of Takeda Shingen, one of the most famous rulers of the period. History Origin The Takeda are descendants of the Emperor Seiwa (858–876), the 56th Emperor of Japan, and are a branch of the Minamoto clan (Seiwa Genji), by Minamoto no Yoshimitsu (1056–1127), son of the Chinjufu-shōgun Minamoto no Yoriyoshi (988-1075), and brother to the famous Minamoto no Yoshiie (1039–1106). Minamoto no Yoshikiyo (1075–1149), son of Yoshimitsu, was the first to take the name of Takeda, which he took when his father granted him Takeda domain in Hitachi Province; thereafter, he was known as Takeda Yoshikiyo. Kamakura to early Azuchi–Momoyama periods In the 12th century, at the end of the Heian period, the Takeda family-controlled Kai Province. Along with a number of other families, they supported their cousin Minamoto no Yoritomo against the Taira clan in the Genpei War (1180–85). When Yoritomo was first defeated at Ishibashiyama (1181), Takeda Nobuyoshi (1128–86) was applied for help, and the Takeda sent an army of 25,000 soldiers to support Yoritomo. Takeda Nobumitsu (1162–1248), son of Nobuyoshi, fought against the Taira, against Kiso Yoshinaka (1184), distinguished himself in the Battle of Ichinotani (1184), and was appointed Shugo (Governor) of Kai province. He also fought against the Northern Fujiwara (1189) and against Wada Yoshimori (1213). During the Jōkyū War, he helped the Hōjō, and led 50,000 soldiers as 'Daishogun of the Tosando' , and in reward received the governorship of Aki province (1221). Takeda Nobuhide (1413–40), eldest son of the Takeda Nobushige (1390–1465), Shugo of Aki, helped the 6th shogun Ashikaga Yoshinori (1394–1441) against the revolt of Isshiki Yoshitsura and was granted the governorship of Wakasa province (1440). Takeda Nobukata (1420–71) inherited the titles of Shugo of Wakasa from his brother Nobuhide, and that of Shugo of Aki from his father Nobushige. During the Ōnin War (1467–77) he occupied Tango province that belonged to Isshiki Yoshinao and received the governorship of Tango province (1469). His brother Takeda Kuninobu (1437–90) inherited the titles of Shugo of Aki, Wakasa, and Tango provinces, but lost Tango in 1474. Until the Sengoku period, the Takeda were Shugo of the provinces of Kai (since Yoritomo), Aki (since 1221), and Wakasa (since 1440).
