Well, the effect of militarism changed by how all the major countries made alliances with each other. Another effect is nationalism, which is pride for one's country. That feeling was directed towards other countries, treating others that they were inferior. This helped spark the Great War. The major countries, Britain, France, and Russia, aligned with each other. They were called the triple Entente. The other 3 big countries, the Austrian-Hungarian Empire, the Germans, and the Italians, were the opposition to the Triple Entente. They were called the Triple Alliance.
