Emperor Chūkyō

Emperor Chūkyō (1218–1234) was the 85th emperor of Japan, though his reign lasted barely two months in 1221. At the age of two he succeeded his father Emperor Juntoku, who abdicated to join Retired Emperor Go-Toba's rising.

When the Jōkyū Incident ended in defeat, the shogunate dethroned the infant in favour of Emperor Go-Horikawa. Long known as the Kujō Dethroned Emperor or the Half-Emperor, he was recognised as an emperor and given the posthumous name Chūkyō in 1870.
