of the little Duke of Valois affected Henrietta greatly. She gave birth to a stillborn daughter in July 1665, but another daughter was born in 1669 who was baptised Anne Marie in 1670. In 1666, her husband's most prominent alleged lover, the Chevalier de Lorraine, became attached to the Orléans household. Lorraine often vied for power within Philippe's household, an unusual arrangement for the time. Henrietta has often been praised as a cultured princess, and her correspondence with Moliere, Racine, La Fontaine, Bussy-Rabutin and others is notable.

Charles abandoned England's Triple Alliance with Sweden and the Dutch Republic in favour of assisting Louis XIV in conquering the Dutch Republic, which he claimed for his wife Queen Maria Theresa as part of her unpaid dowry. Provided that the conquest was successfully completed, England was promised several very profitable ports along one of the major rivers that ran through the
