The Japanese Feudal Wars, primarily occurring from the late 12th to the early 17th centuries, were a series of conflicts among powerful samurai clans. These wars were characterized by battles for control over land and political power, leading to the rise of military leaders known as shoguns. The most notable period was the Sengoku era, marked by constant warfare and shifting alliances. During these conflicts, the Ashikaga and Tokugawa clans emerged as significant players. The wars ultimately culminated in the establishment of the Tokugawa shogunate in 1603, which brought about a long period of peace known as the Edo period. This era significantly shaped Japan's social and political landscape.
