Western betrayal is the view that the United Kingdom, France, and sometimes the United States failed to meet their legal, diplomatic, military, and moral obligations with respect to the Czechoslovak and Polish states during the prelude to and aftermath of World War II. It also sometimes refers to the treatment of other Central and Eastern European states at the time.

The Munich Agreement was an agreement reached in Munich on 30 September 1938, by Nazi Germany, Great Britain, the French Republic, and Fascist Italy. The agreement provided for the German annexation of part of Czechoslovakia called the Sudetenland, where more than three million people, mainly ethnic Germans, lived. The pact is also known in some areas as the Munich Betrayal, because of a previous 1924 alliance agreement and a 1925 military pact between France and the Czechoslovak Republic.
