Tōdō Takatora was a Japanese daimyō of the Tōdō clan from the Azuchi–Momoyama to Edo periods. He rose from relatively humble origins as an ashigaru to become a daimyō.

The Battle of Sekigahara was a decisive battle on October 21, 1600 in what is now Gifu Prefecture, Japan, at the end of the Sengoku period. This battle was fought by the forces of Tokugawa Ieyasu against a coalition of Toyotomi loyalist clans under Ishida Mitsunari, several of which defected before or during the battle, leading to a Tokugawa victory. The Battle of Sekigahara was the largest battle of Japanese feudal history and is often regarded as the most important. Mitsunari's defeat led to the establishment of the Tokugawa shogunate.
