The Northern Fujiwara were a Japanese noble family that ruled the Tōhoku region of Japan during the 12th century as their own realm. They succeeded the semi-independent Emishi families of the 11th century who were gradually brought down by the Minamoto clan loyal to the Imperial Court in Kyoto. Ultimately they were conquered by the Kantō samurai clans led by Minamoto no Yoritomo. The Ōshū Fujiwara were one of the four great clans during the Heian period — the other three were the Minamoto, the Taira, and the Tachibana.
Minamoto No Yoshiie, also known as Hachimantarō, was a Minamoto clan samurai of the late Heian period, and Chinjufu-shōgun.
