The territory of Hesse was delineated only in 1945, as
Greater Hesse, under
American occupation. It corresponds loosely to the medieval
Landgraviate of Hesse. In the 19th century, prior to the
unification of Germany, the territory of what is now Hesse comprised the territories of
Grand Duchy of Hesse (also known as Hesse-Darmstadt), the
Duchy of Nassau, the free city of
Frankfurt, the
Electorate of Hesse (also known as Hesse-Kassel), the
Principality of Waldeck and the
Landgraviate of Hesse-Homburg.
Early history The Central Hessian region was inhabited in the
Upper Paleolithic. Finds of tools in southern Hesse in Rüsselsheim suggest the presence of Pleistocene hunters about 13,000 years ago. A
fossil hominid skull that was found in northern Hesse, just outside the village of Rhünda, has been dated at 12,000 years ago. The
Züschen tomb (German: Steinkammergrab von Züschen, sometimes also Lohne-Züschen) is a prehistoric burial monument, located between
Lohne and
Züschen, near
Fritzlar, Hesse, Germany. Classified as a gallery grave or a Hessian-Westphalian stone
cist (
hessisch-westfälische Steinkiste), it is one of the most important
megalithic monuments in Central Europe. Dating to , it belongs to the Late
Neolithic Wartberg culture. An early
Celtic presence in what is now Hesse is indicated by a mid-5th-century BC
La Tène-style burial uncovered at
Glauberg. The region was later settled by the
Germanic Chatti tribe around the 1st century BC, and the name
Hesse is a continuation of that tribal name. The
ancient Romans had a military camp in Dorlar, and in Waldgirmes directly on the eastern outskirts of Wetzlar was a civil settlement under construction. Presumably, the provincial government for the occupied territories of the right bank of Germania was planned at this location. The governor of Germania, at least temporarily, likely had resided here. The settlement appears to have been abandoned by the Romans after the devastating
Battle of the Teutoburg Forest failed in the year AD 9. The Chatti were also involved in the
Revolt of the Batavi in AD 69. Hessia, from the early 7th century on, served as a buffer between areas dominated by the
Saxons (to the north) and the
Franks, who brought the area to the south under their control in the early sixth century and occupied
Thuringia (to the east) in 531. Hessia occupies the northwestern part of the modern German state of Hesse; its borders were not clearly delineated. Its geographic center is
Fritzlar; it extends in the southeast to
Hersfeld on the river Fulda, in the north to past
Kassel and up to the rivers Diemel and Weser. To the west, it occupies the valleys of the rivers Eder and Lahn (the latter until it turns south). It measured roughly 90 kilometers north–south, and 80 north-west. The area around Fritzlar shows evidence of significant pagan belief from the 1st century on. Geismar was a particular focus of such activity; it was continuously occupied from the Roman period on, with a settlement from the Roman period, which itself had a predecessor from the 5th century BC. Excavations have produced a
horse burial and bronze artifacts. A possible religious cult may have centered on a natural spring in Geismar, called
Heilgenbron; the name "Geismar" (possibly "energetic pool") itself may be derived from that spring. The village of , now a part of
Gudensberg near Fritzlar and less than ten miles from Geismar, was likely an ancient religious center; the basaltic outcrop of Gudensberg is named after Wodan, and a two-meter tall
quartzite megalith called the
Wotanstein is at the center of the village. By the mid-7th century, the Franks had established themselves as overlords, which is suggested by archeological evidence of burials, and they built fortifications in various places, including
Christenberg. By 690, they took direct control over Hessia, apparently to counteract expansion by the Saxons, who built fortifications in
Gaulskopf and
Eresburg across the river Diemel, the northern boundary of Hessia. The
Büraburg (which already had a Frankish settlement in the sixth century) was one of the places the Franks fortified to resist the Saxon pressure, and according to John-Henry Clay, the Büraburg was "probably the largest man-made construction seen in Hessia for at least seven hundred years". Walls and trenches totaling one kilometer in length were made, and they enclosed "8 hectares of a spur that offered a commanding view over Fritzlar and the densely-populated heart of Hessia". Following Saxon incursions into Chattish territory in the 7th century, two
gaue had been established; a Frankish one, comprising an area around
Fritzlar and
Kassel, and a Saxonian one. In the 9th century, the Saxon
Hessengau also came under the rule of the Franconians.
Holy Roman Empire From 962 the land which would become Hesse was part of the
Holy Roman Empire. In the 10th and 11th centuries it was mostly encompassed by the
Western or Rhenish part of the
stem duchy of
Franconia. In the 12th century,
Hessengau passed to the
Landgraviate of Thuringia. As a result of the
War of the Thuringian Succession (1247–1264) the former Thuringian lands were partitioned between the
Wettin Margraviate of Meissen, which gained Thuringia proper, and the new
Landgraviate of Hesse, which remained with the
Ludovingians. From that point on the Ludovingian coat of arms came to represent both Thuringia and Hesse. It rose to prominence under Landgrave
Philip the Magnanimous, who was one of the leaders of German
Protestantism. After Philip's death in 1567, the territory was divided among his four sons from his first marriage (Philip was a
bigamist) into four lines:
Hesse-Kassel (or Hesse-Cassel),
Hesse-Darmstadt,
Hesse-Rheinfels, and the also previously existing
Hesse-Marburg. As the latter two lines died out quite quickly (1583 and 1605, respectively), Hesse-Kassel and Hesse-Darmstadt were the two core states within the Hessian lands. Several collateral lines split off during the centuries, such as in 1622, when
Hesse-Homburg split off from Hesse-Darmstadt, and in 1760 when
Hesse-Hanau split off from Hesse-Kassel. In the late 16th century, Kassel adopted
Calvinism, while Darmstadt remained
Lutheran and consequently the two lines often found themselves on opposing sides of conflicts, most notably in the disputes over Hesse-Marburg and in the
Thirty Years' War, when Darmstadt fought on the side of the Emperor, while Kassel sided with
Sweden and
France. The Landgrave
Frederick II (1720–1785) ruled Hesse-Kassel as a benevolent despot, from 1760 to 1785. He combined
Enlightenment ideas with Christian values,
cameralist plans for central control of the economy, and a militaristic approach toward diplomacy. He funded the depleted treasury of the poor government by loaning 19,000 soldiers in complete military formations to
Great Britain to fight in North America during the
American Revolutionary War, 1776–1783. These soldiers, commonly known as
Hessians, fought under the British flag. The British used the Hessians in several conflicts, including in the
Irish Rebellion of 1798. For further revenue, the soldiers were loaned to other places as well. Most were conscripted, with their pay going to the Landgrave.
Modern history French Revolution and Napoleonic Wars In 1789 the
French Revolution began and in 1794, during the
War of the First Coalition, the
French Republic occupied the
Left Bank of the Rhine, including part of Lower Katzenelnbogen (, Hesse-Kassel's part of the former
County of Katzenelnbogen which was held by the
appanage Hesse-Rotenburg).
Emperor Francis II formally recognised the annexation of the Left Bank in the 1801
Treaty of Lunéville. This led in 1803 to the , a substantial reorganisation (
mediatisation) of the states and territories of the Empire. Several
exclaves of
Mainz were mediatised to
Hesse-Kassel and
Hesse-Darmstadt, and Hesse-Darmstadt also gained the
Duchy of Westphalia from
Cologne, the parts of
Worms on the right-bank of the Rhine, and the former
Free City of
Friedberg.
Nassau-Weilburg gained the right-bank territories of
Trier among other territories.
Orange-Nassau gained the
Prince-Bishopric of Fulda (as the
Principality of Nassau-Orange-Fulda). The
Landgrave of Hesse-Kassel was also elevated to the status of
Prince-Elector (), with his state thereby becoming the
Electorate of Hesse or Electoral Hesse (, being the German-language term for the Empire's
College of Electors). In July 1806 Hesse-Darmstadt, Nassau-Weilburg,
Nassau-Usingen, and the newly merged
Principality of Isenburg became founding members of
Napoleon's
Confederation of the Rhine. Hesse-Darmstadt expanded further in the resulting mediatisation, absorbing numerous small states (including
Hesse-Homburg and much of the territory of the Houses of
Solms, and
Sayn-Wittgenstein). It was also elevated by Napoleon to the status of
Grand Duchy, becoming the
Grand Duchy of Hesse. Orange-Nassau, which refused to join the Confederation, lost
Siegen,
Dillenburg,
Hadamar and
Beilstein to
Berg and Fulda to the
Prince-Primate of the Confederation (and former Elector of Mainz)
Karl Theodor von Dalberg; the remainder of its territory was merged with that of Nassau-Usingen and Nassau-Weilburg in August 1806 to form the
Duchy of Nassau.
Waldeck also joined the Confederation in 1807.
The Holy Roman Empire was dissolved in August 1806, rendering Hesse-Kassel's electoral privilege meaningless. Hesse-Kassel was occupied by the French in October 1806 and the remainder of Lower Katzenelnbogen was annexed to the
French Empire as . The rest of its territory was annexed to the
Kingdom of Westphalia in 1807;
Hesse-Hanau (a
secundogeniture of Hesse-Kassel) was annexed to the
Grand Duchy of Frankfurt in 1810 along with the other territories held by the Prince-primate: Frankfurt, Fulda,
Aschaffenburg and
Wetzlar. As a result of the
German campaign of 1813 the Kingdom of Westphalia and the Grand Duchy of Frankfurt were dissolved and Hesse-Kassel and Hesse-Hanau were restored; Orange-Nassau was also restored in its territories previously lost to Berg. As a result of the 1815
Congress of Vienna Hesse-Kassel gained Fulda (roughly the western third of the former Prince-Bishopric, the rest of which went to
Bavaria and
Saxe-Weimar-Eisenach) from Frankfurt and part of Isenburg, while several of its small northern
exclaves were absorbed into
Hanover, some small eastern areas were ceded to Saxe-Weimar-Eisenach and Lower Katzenelnbogen was ceded to Nassau. Hesse-Darmstadt lost the Duchy of Westphalia and the Sayn-Wittgensteiner lands to the
Prussian
Province of Westphalia but gained territory on the left bank of the Rhine centred on Mainz, which became known as
Rhenish Hesse (), and the remainder of Isenburg. Orange-Nassau, whose ruler was now also King
William I of
the Netherlands and Grand Duke of Luxembourg, was ceded to Prussia but most of its territory aside from Siegen was then ceded on to Nassau. Hesse-Homburg and the
Free City of Frankfurt were also restored. While the other former Electors had gained other titles, becoming either Kings or
Grand Dukes, the Elector of Hesse-Kassel alone retained the anachronistic title of Prince-Elector; a request to be recognised as "King of the
Chatti" () was rejected by the Congress. Following mediation, the Congress of Vienna had significantly fewer states remained in the region that is now Hesse: the Hessian states, Nassau, Waldeck and Frankfurt. The Kingdoms of Prussia and Bavaria also held some territory in the region. The Congress established the
German Confederation, of which they all became members. Hesse-Hanau was (re-)absorbed into Hesse-Kassel in 1821.
German Empire In the 1866
Austro-Prussian War the states of the region allied with
Austria were defeated during the
Campaign of the Main. Following Prussia's victory and dissolution of the German Confederation, Prussia annexed Electoral Hesse, Frankfurt, Hesse-Homburg, Nassau and small parts of Bavaria and the Grand Duchy of Hesse, which were then combined into the
Province of Hesse-Nassau. The name survived, denoting the region around Kassel. The Grand Duchy of Hesse retained its autonomy in defeat because a greater part of the country was situated south of the river
Main and it was feared that Prussian expansion beyond the Main might provoke France. However,
Upper Hesse (: the parts of Hesse-Darmstadt north of the Main around the town of
Gießen) was incorporated into the
North German Confederation (), a tight federation of German states established by Prussia in 1867, while also remaining part of the Grand Duchy. In 1871, after France's defeat in the
Franco-Prussian War, the whole of the Grand Duchy joined the
German Empire. Around the turn of the 20th century, Darmstadt was one of the centres of the
Jugendstil. Until 1907, the Grand Duchy of Hesse used the Hessian red and white lion
barry as its coat-of-arms.
Weimar and Nazi periods The
revolution of 1918 following the German defeat in
WWI transformed Hesse-Darmstadt from a monarchy to a republic, which officially renamed itself the
People's State of Hesse (). The state parliament, or
Landtag consisted of 70 deputies elected on the basis of
proportional representation. There were six
Landtag elections between 1919 and 1932. Following the
Nazi seizure of power in Berlin, the
Landtag was formally abolished as a result of the "
Law on the Reconstruction of the Reich" of 30 January 1934, which replaced the German
federal system with a
unitary state. The parts of Hesse-Darmstadt on the left bank of the Rhine (Rhenish Hesse), as well as those right-bank areas of Hesse-Darmstadt and Hesse-Nassau within of Koblenz or Mainz
were occupied by French troops until 1930 under the terms of the
Versailles peace treaty that officially ended World War I in 1919. The Kingdom of Prussia became the
Free State of Prussia, of which Hesse-Nassau remained a province. In 1929 the
Free State of Waldeck was dissolved and incorporated into Hesse-Nassau. In 1932
Wetzlar (), formerly an exclave of the Prussian
Rhine Province situated between Hesse-Nassau and the Grand Duchy's Upper Hesse, was transferred to Hesse-Nassau. The former Hessian exclave of
Rinteln (, the Hessian part of the former
County of Schaumburg) was also detached and transferred to the
Province of Hanover. On 1 July 1944 the Prussian Province of Hesse-Nassau was formally divided into the provinces of
Kurhessen and
Nassau. At the same time the former Hessian
Schmalkalden exclaves (), together with the of the
Province of Saxony, were transferred to
Thuringia. The territories of the new provinces did not directly correspond with their pre-1866 namesakes but rather with the associated NSDAP :
Gau Electoral Hesse and
Gau Hesse-Nassau (excluding the areas which were part of the People's State of Hesse).
Post-World War II After
World War II, the Hessian territory west of the Rhine
was again occupied by France, while the rest of the region was part of the
US occupation zone. On 17 September 1945 the
Wanfried agreement adjusted the border between American-occupied Kurhessen and
Soviet-occupied Thuringia. The United States proclaimed the state of
Greater Hesse () on 19 September 1945, out of the People's State of Hesse and most of what had been the Prussian Provinces of Kurhessen and Nassau. The French incorporated their parts of Hesse (Rhenish Hesse) and Nassau (as ) into the newly founded state of
Rhineland-Palatinate () on 30 August 1946. On 4 December 1946, Greater Hesse was officially renamed . Hesse in the 1940s received more than a million
displaced ethnic Germans. Due to its proximity to the
Inner German border, Hesse became an important location of
NATO installations in the 1950s, especially military bases of the US
V Corps and
United States Army Europe. The first elected minister president of Hesse was
Christian Stock, followed by
Georg-August Zinn (both
Social Democrats). The German Social Democrats gained an absolute majority in 1962 and pursued progressive policies with the so-called . The
CDU gained a relative majority in the 1974 elections, but the Social Democrats continued to govern in a coalition with the
FDP. Hesse was first governed by the CDU under
Walter Wallmann during 1987–1991, replaced by a SPD-Greens coalition under
Hans Eichel during 1991–1999. From 1999, Hesse was governed by the CDU under
Roland Koch (retired 2010) and
Volker Bouffier (incumbent as of 2020).
Frankfurt during the 1960s to 1990s developed into one of the major cities of West Germany. As of 2016, 12% of the total population of Hesse lived in the city of Frankfurt. == Geography ==
