What situation best illustrates a policy of appeasement?

A classic example of a policy of appeasement is the Munich Agreement of 1938, where Britain and France allowed Nazi Germany to annex the Sudetenland region of Czechoslovakia in hopes of preventing a larger conflict. This decision was made despite the fact that it undermined Czechoslovak sovereignty and emboldened Adolf Hitler. The policy ultimately failed, as it did not stop Germany's expansionist ambitions, leading to World War II.
