Rhineland

At the earliest historical period, the territories between the Ardennes and the Rhine were occupied by the Treveri, the Eburones and other Celtic tribes, who, however, were all more or less modified and influenced by their Germanic neighbors. On the East bank of the Rhine, between the Main and the Lahn, were the settlements of the Mattiaci, a branch of the Germanic Chatti, while farther to the north were the Usipetes and Tencteri.[3]

Roman and barbarian parts of the Rhineland

Julius Caesar conquered the Celtic tribes on the West bank, and Augustus established numerous fortified posts on the Rhine, but the Romans never succeeded in gaining a firm footing on the East bank. As the power of the Roman empire declined the Franks pushed forward along both banks of the Rhine, and by the end of the 5th century had conquered all the lands that had formerly been under Roman influence. By the 8th century, the Frankish dominion was firmly established in western Germania and northern Gaul.

On the division of the Carolingian Empire at the Treaty of Verdun the part of the province to the east of the river fell to East Francia, while that to the west remained with the kingdom of Lotharingia.[3]

By the time of Emperor Otto I (d. 973) both banks of the Rhine had become part of the Holy Roman Empire, and in 959 the Rhenish territory was divided between the duchies of Upper Lorraine, on the Mosel, and Lower Lorraine on the Meuse.

As the central power of the Holy Roman Emperor weakened, the Rhineland disintegrated into numerous small independent principalities, each with its separate vicissitudes and special chronicles. The old Lotharingian divisions became obsolete, and while the Lower Lorraine lands were referred to as the Low Countries, the name of Lorraine became restricted to the region on the upper Moselle that still bears it. After the Imperial Reform of 1500/12, the territory was part of the Lower Rhenish–Westphalian, Upper Rhenish, and Electoral Rhenish Circles. Notable Rhenish Imperial States included:

• the ecclesiastical electorates of Cologne (without Westphalian possessions) and Trier
• the duchies of Jülich, Cleves, and Berg, forming the United Duchies of Jülich-Cleves-Berg from 1521
• the County of Sponheim and numerous further Imperial Counties
• the Free Imperial Cities of Aachen and Cologne.

In spite of its dismembered condition and the sufferings it underwent at the hands of its French neighbors in various periods of warfare, the Rhenish territory prospered greatly and stood in the foremost rank of German culture and progress. Aachen was the place of coronation of the German emperors, and the ecclesiastical principalities of the Rhine played a large role in German history.[3]

At the Peace of Basel in 1795, the whole of the left bank of the Rhine was taken by France. The population was about 1.6 million in numerous small states. In 1806, the Rhenish princes all joined the Confederation of the Rhine, a puppet of Napoleon. France took direct control of the Rhineland until 1814 and radically and permanently liberalized the government, society and economy. The Coalition of France's enemies made repeated efforts to retake the region, but France repelled all the attempts.[4]

The French swept away centuries worth of outmoded restrictions and introduced unprecedented levels of efficiency.[5] The chaos and barriers in a land divided and subdivided among many different petty principalities gave way to a rational, simplified, centralized system controlled by Paris and run by Napoleon's relatives. The most important impact came from the abolition of all feudal privileges and historic taxes, the introduction of legal reforms of the Napoleonic Code, and the reorganization of the judicial and local administrative systems. The economic integration of the Rhineland with France increased prosperity, especially in industrial production, while business accelerated with the new efficiency and lowered trade barriers. The Jews were liberated from the ghetto. There was limited resistance; most Germans welcomed the new regime, especially the urban elites, but one sour point was the hostility of the French officials toward the Roman Catholic Church, the choice of most of the residents.[6] The reforms were permanent. Decades later workers and peasants in the Rhineland often appealed to Jacobinism to oppose unpopular government programs, while the intelligentsia demanded the maintenance of the Napoleonic Code (which stayed in effect for a century).[7][8]

A Prussian influence began on a small scale in 1609 by the occupation of the Duchy of Cleves. A century later, Upper Guelders and Moers also became Prussian. The Congress of Vienna expelled the French and assigned the whole of the lower Rhenish districts to Prussia, who left them in undisturbed possession of the liberal institutions to which they had become accustomed under the French.[3] The Rhine Province remained part of Prussia after Germany was unified in 1871.[9]

The occupation of the Rhineland took place following the Armistice with Germany of 11 November 1918. The occupying armies consisted of American, Belgian, British and French forces. Under the Treaty of Versailles, German troops were banned from all territory west of the Rhine and within 50 kilometers east of the Rhine.

In 1920, under massive French pressure, the Saar was separated from the Rhine Province and administered by the League of Nations until a plebiscite in 1935, when the region was returned to Germany. At the same time, in 1920, the districts of Eupen and Malmedy were transferred to Belgium (see German-Speaking Community of Belgium).

Shortly after, France completely occupied the Rhineland, strictly controlling all important industrial areas. The Germans responded with passive resistance and hyperinflation; the French gained very little of the reparations they wanted. French troops did not leave the Rhineland until 1925.

On 7 March 1936, in violation of the Treaty of Versailles, German troops marched into the Rhineland and other regions along the Rhine. German territory west of the Rhine had been off-limits to the German military.

In 1945, the Rhineland was the scene of major fighting as the Allied forces overwhelmed the German defenders.[10]

In 1946, the Rhineland was divided into the newly founded states of Hesse, North Rhine-Westphalia, and Rhineland-Palatinate. North Rhine-Westphalia is one of the prime German industrial areas, containing significant mineral deposits, (coal, lead, lignite, magnesium, oil, and uranium) and water transport. In Rhineland-Palatinate agriculture is more important, including the vineyards in the Ahr, Mittelrhein, and Mosel regions.
