石敬瑭
After Lady Feng was widowed, her adoptive brother-in-law Shi Chonggui (Shi Jingtang's biological nephew, whom he also adopted as a son) became infatuated with her. (Shi Chonggui himself had been widowed after the death of his first wife Lady Zhang, who had carried the title of Lady of Wei.) Sometime after Shi Jingtang died in 942, he married her — even before Shi Jingtang was buried, displeasing Shi Jingtang's wife Empress Dowager Li, but who could do nothing about it — even though he claimed to have married her with the empress dowager's agreement. In 943, he created her empress.
