室町幕府
The Ashikaga shogunate was established when Ashikaga Takauji was appointed "Shōgun" after overthrowing the Kenmu Restoration shortly after having overthrown the Kamakura shogunate in support of Emperor Go-Daigo. The Ashikaga clan governed Japan from the Imperial capital of Heian-kyō (Kyoto) as "de facto" military dictators along with the "daimyō" lords of the "samurai" class. The Ashikaga shogunate began the Nanboku-chō period between the Pro-Ashikaga Northern Court in Kyoto and the Pro-Go-Daigo Southern Court in Yoshino until the South conceded to the North in 1392. The Ashikaga shogunate collapsed upon outbreak of the Ōnin War in 1467, entering a state of constant civil war known as the Sengoku period, and was finally dissolved when "Shōgun" Ashikaga Yoshiaki was overthrown by Oda Nobunaga in 1573.
