The Nazis, together with their Sudeten German allies, demanded incorporation of the region into Nazi Germany to escape "oppression", in fact to destroy the Czechoslovak state. While the Czechoslovak government mobilized its troops, the Western powers urged it to comply with Germany believing that they could prevent or postpone a general war by appeasing Hitler.

British Prime Minister Neville Chamberlain met with Adolf Hitler in Berchtesgaden on 15 September and agreed to the cession of the Sudetenland. Three days later, French Prime Minister Édouard Daladier did the same. No Czechoslovak representative was invited to these discussions. Chamberlain met Hitler in Godesberg on September 22 to confirm the agreements. Hitler however, aiming to use the crisis as a pretext for war, now demanded not only the annexation of the Sudetenland but the immediate military occupation of the territories, giving the Czechoslovakian army no time to adapt their defence measures to the new borders. To achieve a solution, Italian prime minister Benito Mussolini suggested a conference of the major powers in Munich and on September 29, Hitler, Daladier and Chamberlain met and agreed to Mussolini's proposal (actually prepared by Hermann Göring) and signed the Munich Agreement accepting the immediate occupation of the Sudetenland. The Czechoslovak government, though not party to the talks, promised to abide by the agreement on September 30. The Sudetenland was relegated to Germany between October 1 and October 10, 1938. ---------------- After the end of World War II, the Potsdam Conference in 1945 determined that Sudeten Germans would have to leave Czechoslovakia. As a consequence of the immense hostility against all Germans that had grown within Czechoslovakia due to Nazi behavior, the overwhelming majority of Germans were expelled.http://en.wikipedia.org/wiki/Sudetenland
