Which of the following is a long-term factor that contributed to World War I?

• A. Militarism
• B. Alliances
• C. Assassination
• D. Immediate mobilization

Answer: (A)

Militarism means a sustained buildup of military power and a belief that national security and policy should be shaped by military strength. In the decades before World War I, many nations expanded armies and navies, instituted conscription, and developed detailed mobilization plans, often under the influence of military leaders. This created a climate where war was seen as a legitimate instrument of policy and where rapid mobilization and showing force were valued as credibility and deterrence. The resulting arms race and the pervasive sense that conflict was possible made regional disputes more likely to spiral into a larger war. The assassination is best understood as a triggering event rather than a long-term trend, and immediate mobilization describes actions taken in a crisis rather than a persistent attitude that set up the entire conflict. Alliances matter and operate within a militarized era, but militarism is the overarching long-term factor that fostered the environment in which alliances and crises interacted to produce World War I.
