(SHOH-guh-nate) The government of medieval Japan in which the Shogun, a military and civil regent, served as the actual leader, while the emperor was the symbolic head of the state and religion. There were three shogunates throughout Japanese history - 1) the Kamakura Shogunate (1192–1333), 2) the Ashikaga Shogunate (1336–1573), and 3) the Tokugawa Shogunate (1603–1868).
