Fujiwara no Koretada
Fujiwara no Koretada (924–972) was the eldest son of Fujiwara no Morosuke and maternal uncle of Emperors Reizei and En'yū, whose mother was his sister Anshi. In 951 Emperor Murakami made him a compiler of the imperial waka anthology, and his poetry later entered the Hyakunin Isshu.
He rose to minister of the right in 970 and, after his uncle Saneyori died, became sesshō regent; in 971 he was named grand minister. He supervised En'yū's enthronement early in 972 but fell ill and died that November, aged forty-nine.
