German Empire
The German Empire or Germany ("Deutsches Reich" or "Deutsches Kaiserreich"or Deutschland in the German language) is the name for a group of German countries from January 18, 1871 to November 9, 1918. This is from the Unification of Germany when Wilhelm I of Prussia was made German Kaiser to when the third Emperor Wilhelm II was removed from power at the end of the First World War. In the 1920s, German nationalists started to call it the "Second Reich".
