Hesse
After World War II, the Hessian territory west of the Rhine was again occupied by France, whereas the rest of the region was part of the US occupation zone. The French separated their part of Hesse from the rest of the region and incorporated it into the newly founded state of Rhineland-Palatinate (Rheinland-Pfalz). The United States, on the other side, proclaimed the state of Greater Hesse ("Groß-Hessen") on 19 September 1945, out of Hesse-Darmstadt and most of the former Prussian province of Hesse-Nassau.
