一條天皇
In his reign there was a severe struggle between the Fujiwara clan over who would be appointed "kampaku". Emperor En'yū followed his mother's advice and favored Fujiwara no Kanemichi, his maternal uncle. He had only one son, later the emperor Emperor Ichijō by Senshi, a daughter of his uncle Fujiwara no Kaneie, who was another brother of his mother. He made the daughter of Kanemichi the empress consort, though she bore no children. Senshi and her father Kaneie were angry at this elevation of their rival and were absent from the court for a long time, staying at the mansion of Kaneie with the child.
