Final answer:
The re-militarization of the Rhineland marked a significant escalation in Hitler's challenge to the Treaty of Versailles, increasing his influence, escalating tensions, and contributing to the breakdown of diplomacy that led to World War II.
Step-by-step explanation:
Significance of the Re-militarization of the Rhineland
The re-militarization of the Rhineland in 1936 was a pivotal event in the history leading up to World War II. It involved German troops entering the previously demilitarized zone along the French border, which was a clear violation of the Treaty of Versailles. This bold move by Adolf Hitler directly challenged the post-World War I international order and the restrictions placed on Germany's military capabilities.
The act significantly increased Hitler's influence within Germany and on the international stage. It further escalated tensions in Europe, as it reflected Germany's disregard for the compliance that had been expected of it. Most notably, the re-militarization contributed to the overall breakdown of international diplomacy and signaled to the world that Hitler was willing to take aggressive actions to achieve his aims, setting the stage for subsequent expansions and ultimately, the onset of World War II.
Appeasement played a crucial role in the aftermath, with Britain and France choosing not to intervene, a decision that emboldened Hitler and contributed to future aggressive moves, such as the annexation of Austria and occupation of Czechoslovakia.
