Teishi (976-1000) was Regent Michitaka's daughter. Married to Emperor Ichijô when he was ten and she fourteen, she was given the position of empress almost immediately. During the years of her father's regency, Teishi's salon was known for its literary verve, and included among its members Sei Shônagon, author of the famous Pillow Book. Shônagon's evocative descriptions of court life are all based on the people and happenings in Teishi's court. The story about Teishi's mania for cats in my novel comes directly from an incident in the Pillow Book.Teishi's luck began to run out after her brothers Korechika and Taka'ie, her only backers at court, were disgraced and sent into exile. It did not help that Emperor Ichijô was so afraid of displeasing Michinaga that he did not visit Teishi after the birth of their first child, a daughter, in 996. Ichijô managed to get Teishi back to the palace the following year, but two years later, when she was pregnant again and preparing for her formal departure, Michinaga humiliated her by mounting his own expedition to Uji on the same day, sweeping all the royal courtiers into his own entourage.
