Ise

The Ise were a bureaucratic samurai house who claimed descent from the Kanmu Taira line of Ise. At the end of the Kamakura period Taira no Toshitsugu took the name Ise after his appointment as governor of Ise, and by 1330 Ise Munetsugu was serving the Ashikaga in Kazusa.

In 1379 Ise Sadatsugu became chief administrator of the Muromachi shogunate's Mandokoro, an office his descendants inherited. Ise Sadachika raised shōgun Ashikaga Yoshimasa and dominated politics until his fall in 1466; his recall during the Ōnin War drove Ashikaga Yoshimi into the western camp.

Ise Sadataka was killed in Kyoto in 1562. The Bitchū Ise branch produced Hōjō Sōun, founder of the Later Hōjō. In the Edo period the main line served as hatamoto and became the authoritative house of the Ise school of warrior etiquette under Ise Sadatake.
