How did alliances contribute to the tension and conflict between European nations?

Alliances in Europe, particularly in the years leading up to World War I, created a web of obligations that heightened tensions among nations. Countries were bound to defend their allies, which meant that conflicts involving one nation could quickly escalate into larger confrontations. This interconnectedness fostered an atmosphere of mistrust and competition, as nations sought to strengthen their positions through military pacts. Ultimately, these alliances transformed regional disputes into global conflicts, contributing significantly to the outbreak of war.
