Battle of Sekigahara
The Battle of Sekigahara (Shinjitai: ; Kyūjitai: , Hepburn romanization: "Sekigahara no Tatakai") was a decisive battle on October 21, 1600 (Keichō 5, 15th day of the 9th month) 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, several of which defected before or during the battle, leading to a Tokugawa victory. The Battle of Sekigahara was the largest and most important battle of Japanese feudal history, and led to the establishment of the Tokugawa shogunate.
