(The Tokugawa clan (Tokugawa-shi or Tokugawa-uji?) was a powerful daimyo family of Japan. They nominally descended from Emperor Seiwa (850–880) and were a branch of the Minamoto clan (Seiwa Genji) by the Nitta clan. However, the early history of this clan remains a mystery. Members of the clan ruled Japan as Shoguns from 1603 to 1867).
