The Battle of Sekigahara marked a pivotal conflict in Japanese history leading to the establishment of the Tokugawa Shogunate.Sekigahara was the greatest samurai battle in history. Japan had long been at civil war until brought under the rule of Oda Nobunaga, and then, following his death at the hands of a traitorous general, that of Toyotomi Hideyoshi. It was Hideyoshi who completed the unification of Japan and ushered in a period of peace.After Hideyoshis death in 1598, a power struggle emerged between those loyal to the Toyotomi, and those who supported the second most powerful warlord, Tokugawa Ieyasu. With Hideyoshi gone, Ieyasu made moves that brought the ire of a number of his contemporaries, and soon the entire country was divided into two great armies, East and West. Leading the loyalist cause was Ishida Mitsunari, who gathered a force of around 130,000 samurai, while the Tokugawa commanded just 80,000.Both sides hurried to seize strategically vital highways and castles. These attacks and sieges culminated in the decisive Battle of Sekigahara. Fought on 21 October 1600, the battle lasted just six hours, but saw the deaths of an estimated 30,000 samurai, the destruction of a number of noble families and the creation of the Tokugawa Shogunate that was to rule Japan for 260 years of relative peace.
