- Great Britain: British Prime Minister Neville Chamberlain pursued a policy of appeasement in an attempt to avoid war with Germany. This included the Munich Agreement of 1938, in which Britain and France agreed to allow Germany to annex the Sudetenland region of Czechoslovakia.
- France: French Prime Minister Édouard Daladier also pursued a policy of appeasement, believing that it was the only way to avoid a war with Germany. He agreed to the Munich Agreement and supported Chamberlain's efforts to negotiate with Hitler.
- Italy: Italian dictator Benito Mussolini was a key figure in the appeasement of Nazi Germany. He supported Hitler's territorial claims and played a role in the Munich Agreement.
- Soviet Union: Soviet leader Joseph Stalin also played a role in the appeasement of Nazi Germany. He signed the Molotov-Ribbentrop Pact with Hitler in 1939, which divided Poland between Germany and the Soviet Union.
These countries were all involved in the appeasement of Nazi Germany in the years leading up to World War II. Their actions helped to embolden Hitler and make war more likely.
