Emperor Go-Horikawa

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

This 13th-century sovereign was named after the 10th-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."

Events of Go-Horikawa's life
In 1221, because of the Jōkyū Incident, an unsuccessful attempt by Emperor Go-Toba to seize real power, the Kamakura shogunate completely excluded those of the imperial family descended from Emperor Go-Toba from the Chrysanthemum throne, thus forcing Emperor Chūkyō to abdicate. After the Genpei War, he, as the grandson of the late Emperor Takakura, who was also a nephew of the then-exiled Retired Emperor Go-Toba, and Chūkyō's first cousin, was enthroned as Go-Horikawa. He ruled from July 29, 1221 to October 26 (?), 1232.


 * 1221 (Jōkyū 3, 9th day of the 7th month): In the 1st year of what is now considered to have been Chūkyō-tennō's reign (仲恭天皇一年), he abruptly abdicated without designating an heir; and contemporary scholars then construed that the succession (‘‘senso’’) was received by a grandson of former Emperor Go-Toba.
 * 1221 (Jōkyū 3, 1st day of the 12th month): Emperor Go-Horikawa acceded to the throne (‘‘sokui’’).

As Go-Horikawa was only ten-years-old at this time, his father Imperial Prince Morisada acted as cloistered emperor under the name Go-Takakura-in.

In 1232, he began his own cloistered rule, abdicating to his 1-year-old son, Emperor Shijō. However, he had a weak constitution, and his cloistered rule lasted just under two years before he died.

Emperor Go-Horikawa's Imperial tomb (misasagi) is at Sennyū-ji in the Nochi no Tsukinowa no Higashiyama no misasagi (後月輪東山陵).

Kugyō
Kugyō (公卿) is a collective term for the very few most powerful men attached to the court of the Emperor of Japan in pre-Meiji eras.

In general, this elite group included only three to four men at a time. These were hereditary courtiers whose experience and background would have brought them to the pinnacle of a life's career. During Go-Horikawa's reign, this apex of the Daijō-kan included:
 * Sesshō, Konoe Iezane, d. 1242.
 * Sadaijin, Konoe Iemichi, 1204–1224.
 * Udaijin, Fujiwara Kintsugu, 1117–1227.
 * Naidaijin, Saionji Kintsune, 1171–1224.
 * Dainagon
