Kannō disturbance

The Kannō disturbance or Kannō incident (観応擾乱, Kannō Jōran), also called Kannō no juran, was a civil war which developed from antagonisms between shōgun Ashikaga Takauji and his brother, Ashikaga Tadayoshi, thus dividing and weakening the early Ashikaga shogunate. These events are labeled Kannō after the Japanese era or nengō which was proclaimed by the Northern Court during the years 1350 through 1351 in the Nanboku-chō period of Japanese history. One of the main effects of the Disturbance was the re-invigoration of the Southern Court's war effort due to the flow of renegades from Kyoto who followed Tadayoshi to the Southern capital of Yoshino, near Nara.
