The Nanboku-chō Wars were a series of conflicts in Japan during the late 14th and early 15th centuries, primarily between the Northern Court and the Southern Court. These two factions emerged after the Genko War, as rival claimants to the imperial throne sought to establish their legitimacy. The wars were marked by shifting alliances and battles across the country. The conflict ultimately ended in 1392 when the two courts were unified under the Ashikaga shogunate. This resolution led to the establishment of the Muromachi period, which significantly influenced Japanese culture and politics. The Nanboku-chō Wars are a key part of Japan's feudal history.
