Viking raids in the Rhineland
The area known today as the Rhineland begins at the confluence of the Moselle and the Rhine and ends at Emmerich, where the Rhine divides into the Lek and the Waal to form a delta. In the east, the Rhineland ends close to the Rhine itself, being bounded by low mountain ranges such as the Siebengebirge or Bergisches Land. To the west its boundary is less well defined, but in general parlance it runs beyond the present state border with the Netherlands, i.e. east of the Meuse. Because the modern state of Rhineland-Palatinate lies south of the Moselle, the low mountain range of the Eifel north of the river is usually seen as belonging to the Rhineland. Areas south of the Moselle, such as the Hunsrück, are also considered to be part of the Rhineland.
Rhine Province
In 1815, Prussia gained control of the duchies of Cleves, Berg, Gelderland and Jülich, the ecclesiastical principalities of Trier and Cologne, the free cities of Aachen and Cologne, and nearly one hundred small lordships and abbeys which would all be amalgamated into the new Prussian Rhine Province. In 1822 Prussia established the Rhine Province by joining the provinces of Lower Rhine and Jülich-Cleves-Berg. Its capital was Koblenz; it had 8.0 million inhabitants by 1939. In 1920, 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). In 1946, the Rhine Province was divided up between the newly founded states of North Rhine-Westphalia and Rhineland-Palatinate. The town of Wetzlar became part of Hesse.
