Was increasing militarism a cause of world war 1?

Yes, increasing militarism was a significant cause of World War I. European nations engaged in an arms race, building up their military forces and stockpiling weapons, which heightened tensions and fostered an environment of fear and suspicion. This militaristic mindset contributed to the willingness of countries to resort to military solutions for conflicts, ultimately leading to the outbreak of war after the assassination of Archduke Franz Ferdinand in 1914. The belief that military power was essential for national security and prestige further escalated the conflict.
