1601: The Aftermath of Sekigahara—A Sweeping Reshuffle of the Daimyo - Sengoku Shogun Map
Soon after his victory at Sekigahara, Tokugawa Ieyasu carried out a reward and punishment campaign, stripping fiefs from daimyo who had sided with the Western Army while granting increased holdings to those who had backed him. Many daimyo who owed their positions to the Toyotomi were relocated to distant regions such as Chūgoku, Shikoku, and Kyūshū, while the strategic Kinai and Tōkaidō regions were filled with Tokugawa relatives and hereditary vassals, establishing the pattern of daimyo placement that would define the Edo period.
