"Angélique and the King" is a 1959 novel by Anne Golon & Serge Golon, the second novel in the Angélique series. Inspired by the life of Suzanne de Rougé du Plessis-Bellière, known as the Marquise du Plessis-Bellière.
Angélique's marriage to Jeoffrey de Peyrac is thought to be parallel to that of the daughter of Madame de Sévigné, Françoise-Marguerite de Sévigné to the Comte de Grignan.
In 1966, it was adapted into a film titled Angélique et le Roy.
