Emperor Go-Horikawa

Emperor Go-Horikawa (後堀河天皇, Go-Horikawa-tennō) (22 March 1212 – 31 August 1234), was the 86th emperor of Japan who reigned during the Jōō period, according to the traditional order of succession. His reign spanned the years from 1221 through 1232.

This 13th-century sovereign was named after the 11th-century Emperor Horikawa and go- (後), translates literally as "later"; and thus, he is sometimes called the "Later Emperor Horikawa". The Japanese word go has also been translated to mean the "second one;" and in some older sources, this emperor may be identified as "Horikawa, the second," or as "Horikawa II."
