Landgraviate of Hesse-Kassel

The Landgraviate of Hesse-Kassel, spelled Hesse-Cassel during its entire existence, was a state of the Holy Roman Empire. The state was created in 1567 when the Landgraviate of Hesse was divided upon the death of Philip I, Landgrave of Hesse. His eldest son William IV inherited the northern half of the Landgraviate and the capital of Kassel. The other sons received the Landgraviates of Hesse-Marburg, Hesse-Rheinfels and Hesse-Darmstadt. During the Napoleonic reorganisation of the Empire in 1803, the Landgrave of Hesse-Kassel was elevated to an Electorate and Landgrave William IX became an Imperial Elector. Many members of the House of Hesse-Kassel served in the Danish military gaining high ranks and power in the realm due to the fact that many Landgraves were married to Danish princesses. Members of the family who are known to have served Denmark-Norway include Prince Frederik of Hesse-Kassel, Prince Frederick of Hesse-Kassel, and Prince Charles of Hesse-Kassel. It had two votes to the Reichstag: one for itself and one for Hersfeld Abbey. It was later occupied by French troops and became part of the Kingdom of Westphalia, a French satellite state. The Electorate of Hesse was restored at the end of the Napoleonic Wars, though by that time there was no longer an emperor to elect. History The Landgraviate of Hesse-Kassel was founded by William IV the Wise, the eldest son of Philip I. On his father's death in 1567, the Landgraviate of Hesse was divided into four parts. William IV received about half of the territory, with Kassel as his capital. Hesse-Kassel expanded in 1604 when Maurice, Landgrave of Hesse-Kassel inherited the Landgraviate of Hesse-Marburg from his childless uncle, Louis IV, Landgrave of Hesse-Marburg (1537–1604).
