On which side did the Germany fight in World War 1?
The Germans fought for the Central Powers. Or, more accurately, the Central Powers fought for Germany. Germany declared war on France and Russia in on August 1 and 3, and not until several days later was war declared between Austria-Hungary and either of these, or indeed on any country besides Serbia. In effect, Germany began the war unilaterally, and other powers (Austria-Hungary,and later Turkey and Bulgaria) subsequently adhered to her, forming the "Central Powers".
