Maurice of Hesse-Kassel

Maurice of Hesse-Kassel (German: Moritz) (25 May 1572 – 15 March 1632), also called Maurice the Learned,[1] was the Landgrave of Hesse-Kassel (or Hesse-Cassel) in the Holy Roman Empire from 1592 to 1627. Maurice was born in Kassel as the son of William IV, Landgrave of Hesse-Kassel, and of his wife Sabine of Württemberg. Although Maurice had been raised in the Lutheran faith, he converted to Calvinism in 1605. On the principle Cuius regio eius religio, Maurice's subjects were also required to convert to Calvinism.
