Also, Kinexkid, and everyone else, Prussia was never an empire. Ever. The king of Prussia eventually became the German Emperor, but that was after many successful wars and political coups by the Prussians. German didn't exist as a unified country until the Prussians, under the Iron Chancellor Otto von Bismarck, created the German Empire. It was the king of Prussia and German Emperor Wilhelm II that launched Germany into WWII.
