What factors led to the militarism?

  Militarism is a philosophy or system that places great importance on military power. Alfred Vagts, a German historian who served in World War I, defined militarism as the “domination of the military man over the civilian, an undue preponderance of military demands, an emphasis on military considerations”. Militarism was a significant force in several European nations in the years prior to World War I.
