But the Crown Prince Chikahito was the official stepson of Teishi and she raised him in the past so her position was secured.
But her relationship with her stepson became tense, and shortly after enthronement, Emperor Go Suzaku forbade her mother to see her daughter who was involved in a scandal at that time.
As Empress Dowager, her biggest concern was to ensure the succession of her son, Crown Prince Takahito.
So Teishi started to organize a political faction with high ranked nobility to protect and support the crown prince.
In the meantime, Yorimichi arranged for her daughter, Hiroko to become Empress in 1051, with the intention of creating a new heir who could replace Teishi’s son.
The marriage of Emperor Horikawa and Princess Tokushi was Teishi’s idea, to strengthen imperial ties.
