How did one patient warlord end the civil wars?
Tokugawa Ieyasu was a hostage at five, and at Sekigahara several enemy commanders switched to his side before or during the battle.
▶ Start the storyOne patient warlord ended the civil wars by outlasting everyone else, then winning one decisive battle and building a system that made another war unlikely. Tokugawa Ieyasu was the third of the three "" of Japan, after Oda Nobunaga and Toyotomi Hideyoshi. A saying of the time put it this way: reunification was a rice cake that Oda made, Hashiba shaped, and in the end only Ieyasu tasted.
His patience began as a child. Ieyasu, the son of a minor , lived as a under a neighbouring lord on behalf of his father. At five he was abducted by the rival Oda clan, who threatened to execute him unless his father broke with the Imagawa. His father refused. The boy lived anyway, and grew up as a pawn in other men's quarrels.
When Hideyoshi ruled, Ieyasu accepted a move to the Kanto plains, far from Osaka, and built his castle in the fishing village of Edo, now Tokyo. He also preserved his strength while Hideyoshi's armies failed in Korea. After Hideyoshi's death, he met a led by Ishida Mitsunari at Sekigahara on 21 October 1600. Several commanders on the other side before or during the battle, and Ieyasu won. He was appointed shogun in 1603.
Winning was only the start. In 1614 and 1615 the Tokugawa destroyed the Toyotomi clan at the siege of Osaka. Before that, the shogunate had read an inscription on a Toyotomi temple bell as splitting Ieyasu's name in two, a for war. Ieyasu then built rules to keep the lords in line, and the Tokugawa shogunate ruled Japan for two and a half centuries.

Recap
Ieyasu won by waiting, defections and rules, and his successors, not he himself, made the hostage rule of sankin-kōtai compulsory.
💡 A trick to remember it · Oda mixed the rice cake, Hideyoshi shaped it, and the boy who had learned to wait as a hostage was the one who got to eat it.
Surprising fact · The fight at Sekigahara may have been decided before it began, since several commanders had already defected, and historians argue about when.
