Answer
Post-shogunate marked Kamakura's decline. The Kamakura shogunate, established in 1192, had maintained control for over a century. However, by the 14th century, the shogunate had weakened due to internal conflicts and external threats. In 1333, Emperor Go-Daigo attempted to restore imperial rule, leading to the Genkō War. The shogunate was defeated, and the imperial court regained power.
