Answer:
The adoption of the policy of appeasement at the Munich Conference in September 1938 changed Europe by emboldening German aggression and ultimately failing to prevent further conflict. By appeasing Hitler's demands for the Sudetenland region of Czechoslovakia, Britain and France hoped to avoid war and maintain peace in Europe. However, this policy only served to appease Hitler temporarily, as he continued to expand his territorial ambitions. This emboldened Germany's aggressive actions, leading to further annexations and ultimately contributing to the outbreak of World War II in 1939. Appeasement at Munich demonstrated the limitations of diplomatic negotiations in deterring aggressive regimes and underscored the need for stronger collective security measures to preserve peace in Europe.
