The Munich Agreement was a settlement reached in September 1938 between Germany, the United Kingdom, France, and Italy that allowed Nazi Germany to annex the Sudetenland region of Czechoslovakia. This agreement is often cited as a classic example of the policy of appeasement, which aimed to prevent war by conceding to some of the demands of aggressive powers. The Munich Agreement not only failed to secure lasting peace but also highlighted the tensions and instability leading up to World War II.
