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 (南朝, nanchō) had been established in exile in Yoshino, near Nara.[3]
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.[3]

1350–1352 ((Shōhei 5–Shōhei 7): Armed conflict, variously known as the Kannō disturbance or Kannō incident (觀廣擾亂, Kannō Jōran) or Kannō no juran, developed from antagonism between Shōgun Ashikaga Takauji and his brother, Ashikaga Tadayoshi. Disagreement about the influence of Kō no Moronao diminished after death of Moronao. Tadayoshi was ordered to relocate to Kamakura. The brothers eventually reconciled before Tadayoshi's death in 1352.[8]
