佐竹氏
In the Muromachi period (1336–1573), the Satake family's heads served as hereditary governors ("shugo") of Hitachi Province. They were vassals of the Ashikaga shogunate's "Kamakura-kubō", the Kamakura-based official who oversaw the Ashikaga shogunate's affairs in the Kantō region. The Satake clan saw a great deal of military service under the Ashikaga banner.
