Fujiwara no Morosuke

Fujiwara no Morosuke (909–960), known as Kujō-dono, was the second son of the regent Fujiwara no Tadahira and a learned mid-Heian statesman. He married three daughters of Emperor Daigo in succession. Promoted to udaijin in 947, he overshadowed his elder brother Saneyori as the driving force of Emperor Murakami's Tenryaku government, aided by his daughter Anshi, the empress who bore the future emperors Reizei and En'yū.

He died in 960 aged fifty-three, having never become regent himself; under his sons Koretada and Kaneie, his Kujō line became the Fujiwara regent house.
