Emperor Go-Yōzei
The Battle of Sekigahara was the last major battle of the Sengoku period on October 21, 1600. This was a huge battle between the forces loyal to Toyotomi Hideyori versus Tokugawa Ieyasu. Hideyori's Western Army consisted of many clans from Western Japan with a total of 120,000 men. The Eastern Army was 75,000 men strong with clans from Eastern Japan. The decisive victory of the Eastern Army solidified the rule of Tokugawa Ieyasu. In 1603, Ieyasu was appointed with the title of "shōgun" by Emperor Go-Yōzei. This made Ieyasu the nominal ruler of the whole country of Japan. The Tokugawa shogunate was the last shogunate until the Meiji Restoration in 1867.
