Which country was the victim of appeasement at Munich in September 1938?

The country that was the victim of appeasement at Munich in September 1938 was Czechoslovakia. During the Munich Agreement, Britain, France, Italy, and Germany allowed Nazi Germany to annex the Sudetenland, a border region of Czechoslovakia, without the Czechoslovak government's consent. This act of appeasement aimed to prevent a larger conflict but ultimately emboldened Adolf Hitler's aggression and contributed to the outbreak of World War II.
