1467-1603 CE
From 1467 to 1603 CE, the Japanese plunged into an age of warring states and emerged unified by three warlords — the Ōnin War shattering Ashikaga authority, a century of daimyō battling for supremacy with muskets the Portuguese had brought, until Nobunaga conquered by firepower, Hideyoshi invaded Korea with samurai armies, and Tokugawa won the patience game at Sekigahara. From chaos came an order that would last two and a half centuries.
