承久之亂
Because of the sudden death of Emperor Shijō at the age of 10, the question of succession arose. Because the expectations of the court nobility and the Bakufu conflicted, the issue was bitterly contested. Kujō Michiie and the court nobility supported Prince Tadanari (忠成王), a son of Retired Emperor Juntoku, but the "shikken" Hōjō Yasutoki was opposed to the sons of Juntoku because of his involvement in the Jōkyū War. Michiie instead supported Tsuchimikado's son Prince Kunihito as a neutral figure for Emperor. During these negotiations, there was a vacancy on the throne of 11 days.
