This map shows Germany during and after WWI. During WWI, Germany and its allies – the Central Powers – occupied parts of the Balkans and Russia, while on the Western front the war resulted in a stalemate in the trenches of Belgium and the north of France. In the occupied territories, the Central Powers installed either civil or military administrations. The German ‘Etappengebiet’, which were military critical areas just behind the front lines, had a special status. Stamps were issued for many of the occupied territories.
