| The Battle of Sekigahara popularly known as the Battle for the Sundered Realm was a decisive battle on October 21, 1600 (Keichō 5, 15th day of the 9th month) which cleared the path to the Shogunate for Tokugawa Ieyasu. Though it would take three more years for Ieyasu to consolidate his position of power over the Toyotomi clan and the daimyo, Sekigahara is widely considered to be the unofficial beginning of the Tokugawa bakufu, the last shogunate to control Japan. Japan then had a long period of peace after that battle.Even though Toyotomi Hideyoshi unified Japan and consolidated his power following the Siege of Odawara in 1590, his failures in his invasions of Korea significantly weakened the Toyotomi clan's power as well as the loyalists and bureaucrats that continued to serve and support the Toyotomi clan after Hideyoshi's death. Hideyoshi's and his brother Hidenaga's presence kept the two sides from anything more than quarreling, but when both of them died, the conflicts were exacerbated and developed into open hostilities. Since the Toyotomi clan was known to be descended from peasant stock, neither Hideyoshi nor his heir Hideyori would be recognized or accepted as Shogun. Most notably, Katō Kiyomasa and Fukushima Masanori were publicly critical of the bureaucrats, especially Ishida Mitsunari and Konishi Yukinaga. Tokugawa Ieyasu took advantage of this situation, and recruited them, redirecting the animosity to weaken the Toyotomi clan. |
