Germany

Germany participated a lot in World War 1 . First, they declared war on Russia and then they declared war on France . Germany then invades Belgium so Britain declared war on Germany. The Battle of Tannenberg is fought between Germany and Russia , and the Germans ended up defeating them Russian army ( Ducksters ) . I think that was a valid reason for Germany to enter the war because that’s what they signed up for . Austria- Hungary was apart of their alliance, so it was only right fore Germany to join.
