Militarism is the belief that the use of force was an acceptable way to decide political problems.
Many nations had forgotten the horrors of war.
All the Great Powers except for Great Britain had been building large armies and stockpiling weapons.
Many generals developed war plans such as Germany’s Schlieffen Plan.
The Schlieffen Plan was designed to prevent fighting a war on two fronts. They would attack France first and then turn to Russia.
