The Munich Agreement is signed by Adolf Hitler, Benito Mussolini, Neville Chamberlain, and Édouard Daladier; ceding the Sudetenland border regions from Czechoslovakia to Nazi Germany. Upon his return to London, Chamberlain infamously declared that the agreement had brought "peace for our time," a sentiment quickly proven wrong by the impending World War II.
The Czechoslovak government was not included in the negotiations and was given the choice of resisting alone or submitting to the agreement. The Munich Agreement is considered a failed attempt at appeasement and is often referred to as the "Munich Betrayal" because it abandoned Czechoslovakia and only emboldened Hitler, accelerating the path toward World War II.
