The question describes a scenario where a local conflict (Austria-Hungary declaring war on Serbia) rapidly escalated into a larger war involving multiple major powers due to pre-existing military alliances and treaty obligations. We need to identify which historical concept or event best explains this destabilizing effect.
C) Alliance system — The pre-World War I alliance system, which included treaties like the Triple Alliance (Germany, Austria-Hungary, Italy) and the Triple Entente (France, Russia, Great Britain), created a domino effect. When Austria-Hungary declared war on Serbia, Russia mobilized to support Serbia, triggering Germany's mobilization to support Austria-Hungary, and so on, rapidly escalating a regional dispute into a continent-wide war. This perfectly illustrates the destabilizing effect described.
