Rulers of Hesse
Hesse is a region of west-central Germany. Originally the western part of the Landgraviate of Thuringia, in the mid 13th Century it was inherited by the younger son of Henry II, Duke of Brabant, and became a distinct political entity. From the late 16th century it was generally divided into several branches, the most important of which were those of Hesse-Kassel and Hesse-Darmstadt. During the Napoleonic Period, the Landgrave of Hesse-Kassel changed his title to Elector of Hesse (1803), while the Landgrave of Hesse-Darmstadt became the Grand Duke of Hesse and the Rhine (1806). Electoral Hesse was annexed by Prussia in 1866 after the Six Weeks War, but Grand Ducal Hesse lasted until the end of the German monarchies in 1918.
