Jokyu incident

In 1221 in Japan, the Jokyu incident (承久の乱 Jōkyū no ran) was the attempt of Imperial Court to recapture the real power from the Kamakura Shogunate, led by retired Emperor Go-Toba.

The incident completely spoiled the reputation of the Imperial Court as the official ruler of Japan. Instead, the shogunate established the complete dominance in Japan.
