Elisabeth Henriette of Hesse-Kassel

Landgravine Elisabeth Henriëtte von Hessen-Kassel (18 November 1661 – 7 July 1683) was the daughter of William VI, Landgrave of Hesse-Kassel and Hedwig Sophia of Brandenburg (1623–1683) and electoral princess of Brandenburg through her marriage to Frederick I of Prussia. She was the youngest of seven; siblings included Queen Charlotte Amalie, William VII, Luise, Charles I, Philip, and George. She suffered from an unknown illness in 1677 that her mother treated with the milk cure, wherein a teenage Elisabeth suckled from a wet nurse for three weeks and eventually recovered. Years later, on 13 August 1679, she married her cousin, Frederick, Prince Elector of Brandenburg, in Potsdam

Elisabeth Henriëtte died on 7 July 1683 at age 21 from smallpox. Frederick accused his stepmother Dorothea of poisoning her but this was found to be untrue via investigation.
