Sagae

The Sagae were a branch of the Oe clan and took their name from the Sagae estate in Dewa province. Oe no Hiromoto, first head of the Kamakura shogunate's Mandokoro, received the estate's jito post for the Oshu campaign of 1189; his son Chikahiro inherited it and retired there after the failed Jokyu rising of 1221.

In 1333 the clan fought for the Southern Court. Motomasa was killed in 1359 in war against the Shiba; in 1368 the disaster of Urushigawa cost sixty-one clansmen their lives. Peace in 1373 surrendered the northern half of the estate to Shiba Kaneyori, and the head took the name Sagae and built Sagae castle.

After their castle fell in 1574 they leaned on the Date, until Mogami Yoshiaki overran them in 1584 and the last lord Takamoto took his own life. Survivors served the Mogami and other daimyo.
