ABSTRACT
In 1600, Tokugawa Ieyasu defeated his rivals and the supporters of the Toyotomi family in the Battle of Sekigahara. In 1603 the emperor designated him shōgun and made Edo (Tokyo) the seat of government. By 1615 he had eliminated the Toyotomi family, and he tightened his grip on the entire country by establishing a political and social order that brought all segments of the society under his firm control. He and the third shōgun, Iemitsu, adopted and implemented measures that would ensure the security of Tokugawa hegemony.
