Answer:
This was a result of the Munich Agreement, which was signed in 1938 by Germany, Italy, Great Britain, and France. The agreement was a diplomatic effort to prevent the outbreak of another European war by appeasing Nazi Germany and allowing it to annex the Sudeten region of Czechoslovakia, which was heavily populated by Germans. This was seen as a compromise at the time, but ultimately, it only served to further empower Hitler and enable his continued aggression.
