The Japanese Civil Wars refer to a series of conflicts in Japan, primarily during the late 15th to the early 17th centuries. These wars were characterized by power struggles among various feudal lords, known as daimyōs, as they vied for control over territories. The most notable period of conflict was the Sengoku period, which lasted from the mid-15th century until the early 17th century, leading to significant social and political changes. The culmination of these civil wars was the unification of Japan under Tokugawa Ieyasu after the decisive battle of Sekigahara in 1600. This victory established the Tokugawa shogunate, a military government that ruled Japan for over 250 years, bringing relative peace and stability to the nation after decades of warfare.
