The Kenmu Restoration was an effort made by Emperor Go-Daigo to overthrow the ruling Kamakura Shogunate and restore the Imperial House to power in Japan, returning to civilian government after 148 years of "de facto" military government from Kamakura. Go-Daigo launched the Genkō War in 1331 against the Kamakura Shogunate but was defeated and exiled to the Oki Islands. Go-Daigo launched a second uprising and with the assistance of the defected Kamakura general Ashikaga Takauji defeated the Kamakura Shogunate at the siege of Kamakura in 1333. The Imperial House was restored to power but Go-Daigo's policies failed to satisfy his "samurai" supporters and most Japanese people. The Kenmu Restoration was ultimately overthrown when Takauji became "Shōgun" and founded the Ashikaga Shogunate in 1336, beginning the "Northern and Southern Courts" period and the Muromachi period.
