Tokugawa Iemitsu, Japanese shogun (d. 1651)
Tokugawa Iemitsu (徳川 家光, August 12, 1604 – June 8, 1651) was the third shōgun of the Tokugawa dynasty. He was the eldest son of Tokugawa Hidetada with Oeyo, and the grandson of Tokugawa Ieyasu. Lady Kasuga was his wet nurse, who acted as his political adviser and was at the forefront of shogunate negotiations with the Imperial court. Iemitsu ruled from 1623 to 1651; during this period he crucified Christians, expelled all Europeans from Japan and closed the borders of the country, a foreign politics policy that continued for over 200 years after its institution. It is debatable whether Iemitsu can be considered a kinslayer for making his younger brother Tadanaga commit suicide by seppuku.
