  Events of the ''Ninpei'' era

• 1151 : Sadaijin Fujiwara no Yorinaga was given additional powers in the imperial court as "Naï-ken," which gave him the duty and opportunity of reading formal written requests before they should be presented to the emperor. This had been amongst the powers of the Sesshō or the Kampaku. Factions in the court who favored Yorinaga tended to dislike Daijō Daijin Fujiwara Tadamichi, and they employed any means possible to help elevate Yorinaga's position. However, Yorinaga was himself generally disliked because of his capricious character. his tactics and strategy for enhancing his own prestige were focused primarily on diminishing Tadamichi's role in the court.
