Although the diary's sections about the birth of Shōshi's son were meant as a tribute to Michinaga, he is revealed as overly controlling. The child's birth was of enormous importance to Michinaga, who nine years earlier brought his daughter to court as a concubine to Emperor Ichijō; Shōshi's quick ascendence to Empress and status as a mother to the heir consolidated her father's power. The child's birth and its lengthy descriptions, "marked the final tightening of Michinaga's velvet-gloved strangle-hold on imperial succession through his masterful manipulation of marriage politics."
