Son of Terumune Date. As a child, he lost an eye due to illness, thus earning the nickname 'Dokuganryu,' the 'one-eyed dragon.' After his father's death, he was victorious at the Battles of Koriyama and Suriagehara and greatly expanded his own sphere of influence. He overcame many obstacles - from the bad blood between him and Yoshiakira Mogami to dispute over the family estate - to expand his control over all of northern Japan. After Hideyoshi Toyotomi's death, Date joined with Tokugawa in the Battle of Sekigahara.
