What did the Munich Pact in 1938 allow Hitler to do?

The Munich Pact, signed in September 1938, allowed Adolf Hitler to annex the Sudetenland, a region of Czechoslovakia that was largely inhabited by ethnic Germans. This agreement was made by Germany, the United Kingdom, France, and Italy, with the intent of appeasing Hitler and avoiding further conflict in Europe. The pact is often cited as a significant example of the policy of appeasement, as it permitted Hitler to gain territory without facing military opposition, thereby weakening Czechoslovakia and emboldening Nazi Germany. The subsequent actions allowed Hitler to pursue further territorial ambitions in Europe, ultimately contributing to the outbreak of World War II.
