Nanboku-chō overview
During the Meiji period, an Imperial decree dated March 3, 1911, established that the legitimate reigning monarchs of this period were the direct descendants of Emperor Go-Daigo through Emperor Go-Murakami, whose Southern Court had been established in exile in Yoshino, near Nara. Until the end of the Edo period, the militarily superior pretender-Emperors supported by the Ashikaga shogunate had been mistakenly incorporated in Imperial chronologies even though it was known that the Imperial Regalia were not in their possession. This illegitimate Northern Court had been established in Kyoto by Ashikaga Takauji.Change of era
