The Edo period, also known as the Tokugawa period, is the period between 1600 or 1603 and 1868 in the history of Japan, when the country was under the rule of the Tokugawa shogunate and some 300 regional daimyo, or feudal lords. Emerging from the chaos of the Sengoku period, the Edo period was characterized by prolonged peace and stability, urbanization and economic growth, strict social order, isolationist foreign policies, and popular enjoyment of arts and culture.
In 1600, Tokugawa Ieyasu prevailed at the Battle of Sekigahara and established hegemony over most of Japan, and in 1603 was given the title shogun by Emperor Go-Yōzei. Ieyasu resigned two years later in favor of his son Hidetada, but maintained power, and defeated the primary rival to his authority, Toyotomi Hideyori, at the Siege of Osaka in 1615 before his death the next year. Peace generally prevailed from this point on, making samurai largely redundant. Tokugawa shoguns continued Ieyasu's policies of conformity, including a formalization of social classes in a strict hierarchy. By 1639, all foreigners were expelled under the policy of sakoku, with the exception of Dutch traders on the island of Dejima in Nagasaki, beginning a period of isolation. From 1635, daimyō had to spend alternating years in the capital Edo, where their family was required to reside permanently, in a system of "alternate attendance" in order to keep them in check.
