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.Thomas, Julia Adeney. (2001). Reconfiguring modernity: concepts of nature in Japanese political ideology, p. 199 n57, citing Mehl, Margaret. (1997). History and the State in Nineteenth-Century Japan. p. 140-147.
Until the end of the Edo period, the militarily superior pretender-Emperors supported by the Ashikaga shogunate had been mistakenly incorporated in Imperial chronologies despite the undisputed fact that the Imperial Regalia were not in their possession.
This illegitimate Northern Court had been established in Kyoto by Ashikaga Takauji.
Change of era 1332 : The era name was changed to Shōkyō to mark an event or a number of events. The previous era ended and a new one commenced in Genkō 2, the 10th month.Titsingh, p. 287.
In this time frame, Genkō (1331–1333) was the Southern Court equivalent nengō.
