Mary of Great Britain (5 March 1723 – 14 January 1772) was the second-youngest daughter of George II of Great Britain and his wife, Caroline of Ansbach, and Landgravine of Hesse-Kassel as the wife of Frederick II, Landgrave of Hesse-Kassel.

Frederick II (German: Landgraf Friedrich II von Hessen-Kassel) (14 August 1720 – 31 October 1785) was Landgrave of Hesse-Kassel (or Hesse-Cassel) from 1760 to 1785. He ruled as an enlightened despot, and raised money by renting soldiers (called "Hessians") to Great Britain to help fight the American Revolutionary War. He combined Enlightenment ideas with Christian values, cameralist plans for central control of the economy, and a militaristic approach toward international diplomacy.
