Britain and France trade away Czechoslovakia for a promise
What happened
Meeting in Munich, the leaders of Germany, Italy, Britain, and France agreed that Czechoslovakia would surrender its heavily fortified, German-speaking border region, the Sudetenland, to Nazi Germany. Czechoslovakia itself was not invited to the talks and learned the terms only after they were signed. In exchange, Adolf Hitler promised this was his last territorial demand in Europe. British Prime Minister Neville Chamberlain flew home and told cheering crowds he had secured peace for our time. Germany occupied the ceded territory within the following ten days, and by March 1939, less than six months later, German troops had seized the rest of Czechoslovakia outright, promise or no promise.
Why it matters
Munich became the permanent shorthand for appeasement: the idea that conceding to an aggressor's demands can buy real peace rather than simply better terms for the aggressor's next demand. Britain and France's guarantee to defend the next country Hitler threatened, Poland, was a direct, deliberate reversal of the Munich approach, one that would draw them into war within a year.
How we know
The Munich Agreement's text and Chamberlain's own speech survive on film and in the written record, and Hitler's March 1939 occupation of the rest of Czechoslovakia, in flat violation of his own signed promise, is documented in both German and Czechoslovak government records from the time.
