The Battle of Sekigahara took place on October 21, 1600, and was a decisive conflict in Japanese history. It marked the end of the Sengoku period, a time of civil war and social upheaval. The battle was fought between the forces loyal to Tokugawa Ieyasu and those supporting Ishida Mitsunari. Tokugawa's victory established his dominance and led to the unification of Japan. Following the battle, Tokugawa Ieyasu became the shogun, initiating the Edo period, which lasted for over 250 years. This era was characterized by relative peace, stability, and isolation from foreign influence. The outcome of the battle significantly shaped Japan's political landscape for generations.
