Hōgen rebellion

About

The Hōgen rebellion (保元の乱, Hōgen no ran; July 28 – August 16, 1156) was a short civil war fought in order to resolve a dispute about Japanese Imperial succession. The dispute was also about the degree of control exercised by the Fujiwara clan who had become hereditary Imperial regents during the Heian period.

Hōgen no ran produced a series of unanticipated consequences. It created a foundation from which the dominance of the samurai clans would come to be established. It is considered the beginning in a chain of events which would produce the first of three samurai-led governments in the history of Japan.
