The 'Rhine Province' (''Rheinprovinz'' in
German) was a
province of the
Kingdom of Prussia and the
Free State of Prussia from
1822 to
1946. It was created from the provinces of the
Lower Rhine and
Jülich-Cleves-Berg. Its capital was
Koblenz and in 1939 it had 8.0 million inhabitants.
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.
