Following his decisive victory at the Battle of Sekigahara in 1600, Tokugawa Ieyasu consolidated his power by systematically restructuring the status of the daimyo who had opposed him. Under the pretext of allotting rewards, he took the following actions against these lords:

Dispossession and Reduction: Ieyasu stripped profitable lands from prominent daimyo who had fought against him, significantly weakening their economic and military base.12
Transfers: He forcibly transferred many of these opposing daimyo to different regions to disrupt their local power structures.2
Redistribution: The lands confiscated from these defeated lords were either reserved as direct Tokugawa house domains or redistributed among Ieyasu’s own allies and relatives to strengthen his regime.12

Through these measures, Ieyasu effectively neutralized potential threats and established the bakuhan system, ensuring the supremacy of the Tokugawa shogunate for over 260 years.12
