This map compares Germany’s borders before and after the First World War to show the territory it lost after the Peace Treaty of 1919.
There are numerous markings on the map. A legend in the bottom right corner explains them:
• The thick black line with dots above indicates Germany’s borders before the war started in 1914.
• Areas filled in with solid black indicate territory that was ceded away from Germany after the Peace Treaty of 1919.
• Areas filled in with a black background and white dots indicate the “Free territory” of Danzig.
• Areas filled in with a white background and black dots indicate territories that had their ownership decided by plebiscite.
The map goes into further detail to explain which solid black areas were ceded to which country:
• The solid black area in the southwest corner of the map was ceded to France. A small section of it, called the Saar Basin, would become a plebiscite area after 15 years.
• The two small solid black areas just north of the French territory were ceded to Belgium.
• The large solid black area on the eastern side of the map was ceded to Poland.
• The small solid black area in the northeast corner of the map was ceded to the Associated Powers.
• Finally, the small solid black area in the southeast corner of the map was ceded to Czechoslovakia.
