After the end of World War I, the Grand Duchy of Hesse (German: Großherzogtum Hessen) became a republic and changed its name to the "People's State" (implying without monarchy rather than socialist). Its capital was Darmstadt. The state consisted of provinces Upper Hesse (German: Oberhessen, capital Gießen), Starkenburg (capital Darmstadt) and Rhenish Hesse (German: Rheinhessen, capital Mainz).
After the end of World War II, Oberhessen and Starkenburg formed part of the American occupation zone, while Rhenish Hesse, on the left bank of the Rhine, fell within the French occupation zone. On September 19, 1945, American administrators created the new state of Greater Hesse (German: Groß-Hessen) from the Prussian provinces of Hesse and Nassau and from Frankfurt am Main. Greater Hesse was renamed Hesse on December 1, 1946, and later became one of the federal states of West Germany.
Parts of the state on the banks of the Rhine subsequently became part of the Rhineland-Palatinate (Rheinland-Pfalz) federal state.
