What was a significant outcome of the Schlieffen Plan?

The significant outcome of the Schlieffen Plan is best captured by its failure due to underestimating resistance. The Schlieffen Plan was a German military strategy aimed at quickly defeating France through a rapid invasion, then redirecting forces to the Eastern Front for a conflict against Russia. However, during the initial phase of the invasion, German forces faced much stronger resistance from both the French military and the Belgian forces than anticipated. This unexpected resilience delayed the German advance, causing logistical issues and allowing the Allies to regroup and strengthen their defenses.

This failure to achieve a swift victory in France meant that the Germans could not avoid a protracted two-front war, as Russian forces mobilized quicker than expected. Therefore, underestimating the resistance they would encounter was a critical factor that shaped the course of World War I. The miscalculations of the Schlieffen Plan had lasting implications, leading to a stalemate and ultimately the trench warfare that defined much of the conflict.
