Sekigahara, Japan (1600 AD)
The Battle of Sekigahara, better known as the Battle for the Sundered Realm, was the culmination of over a century of warfare and conflict commonly referred to as the Sengoku, or Warring States Period of Japan. Fought between the armies of Toyotomi Hideyori and Tokugawa Ieyasu, it was for all intents and purposes the last great battle of medieval Japan, ushinering in an era of relative peace that would last for over two and a half centuries under the Tokugawa Shogunate. The Battle of Sekigahara was one of the first in the Far East in which firearms (without Europeans using them) played a major role. The battlefield is one of the most popular sites of military interest in Japan.
History
During the latter half of the 15th century, civil war broke out in Japan, fracturing the island realm into countless tiny states vying for territory and power. This era, which lasted from 1467 to 1603, became known as Japan’s Warring States Period (as a counterpart to China’s Warring States Period). Throughout this period, armies became larger and better armed, and castles became more numerous and more heavily fortified. Among the most important military developments of the era was the introduction of firearms to the island by Portuguese traders.
Towards the end of the 1500s, the smaller realms of Japan were increasingly absorbed by the larger, until most of the island came under the domination of the Toyotomi clan. By 1590 almost all of Japan was unified under Toyotomi Hideyoshi. However, the Toyotomi hold on power was weakened both by the fact that they were not aristocrats, as well as by a disastrous war of expansion in Korea.
After the death of Hideyoshi and his brother, a powerful alliance of clans from Eastern Japan was organized to challenge the leadership of Hideyoshi’s son Hideyori. Hideyori marshaled a powerful army to meet the threat; however, unbeknownst to him, several of his allies made secret pacts with the leader of the Eastern clans, Tokugawa Ieyasu, with the intention of abandoning the Toyotomi during the engagement.
Following a series of indecisive skirmishes and sieges, the two armies met at Sekigahara on October 21, 1600. The armies were roughly equal. However, though the western forces initial gained the tactical advantage, the sudden betrayal of several clans left the entire Toyotomi army vulnerable. The battle quickly became a rout, and Hideyori was forced to withdraw. This effectively cemented the ascendency of the Tokugawa clan, which completed the conquest and unification of Japan three years later.
