History of North Rhine-Westphalia
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 the German Reich. 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 into the newly founded states of Hesse, North Rhine-Westphalia and Rhineland-Palatinate.
