源義仲
The Genpei War (1180–1185) marked the war between the Taira (Heike) and Minamoto (Genji) clans; two very prominent Japanese clans of the late-Heian period. The epic "The Tale of the Heike" was composed in the early 13th century in order to commemorate the stories of courageous and devoted samurai. Among those was Tomoe Gozen, servant of Minamoto no Yoshinaka of the Minamoto clan. She assisted Yoshinaka in defending himself against the forces of his cousin, Minamoto no Yoritomo, especially during the Battle of Awazu on February 21, 1184.
