The 'Grand Duchy of Hesse' () was a former state that existed in modern-day
Germany. It was formed in 1806 after the dissolution of the
Holy Roman Empire as a result of the actions of
Napoleon, who then elevated the former
Landgraviate of Hesse-Darmstadt to the level of grand duchy. For this reason, this state was occasionally known simply as 'Hesse-Darmstadt'.
History
Due to Hesse-Darmstadt's membership of Napoleon's
Confederation of the Rhine, it was forced to cede a considerable amount of territory at the 1815
Congress of Vienna. The territory of the
Duchy of Westphalia, which Hesse-Darmstadt received from the 1803 ''
Reichsdeputationshauptschluss'', was ceded to the
Kingdom of Prussia. However, it received some territory on the western bank of the
Rhine, including the important federal fortress at
Mainz.
The
Grand Duchy changed its name to the 'Grand Duchy of Hesse and by Rhine' () in 1816.
In 1867, the northern half of the Grand Duchy (Upper Hesse) became a part of the
North German Confederation, while the half of the Grand Duchy south of the Main (
Starkenburg and
Rhenish Hesse) remained outside. In 1871, it became a constituent state of the German Empire. The last Grand Duke,
Ernst Ludwig (a grandson of
Queen Victoria and brother to
Empress Alexandra of
Russia), was forced from his throne at the end of
World War I, and the state was renamed the '
Volksstaat Hessen' (People's State of Hesse).
The majority of the state combined with
Frankfurt am Main, the Waldeck area (Rhine-Province) and the former Prussian province of
Hesse-Nassau to form the new state of
Hesse following the
Second World War. Excepted was the Montabaur district from Hessen-Nassau and that part of Hessen-Darmstadt on the left bank of the Rhine (
Rhenish Hesse) became part of the
Rhineland-Palatinate state. (Bad) Wimpfen - an exclave of Hessen-Darmstadt - became part of Baden-Württemberg, district of Sinsheim.
