Failure of Appeasement Appeasement meant agreeing to the demands of another nation in order to avoid conflict.During the 1930s, politicians in Britain and France began to believe that the Treaty of Versailles was unfair to Germany and that Hitler's actions were understandable and justifiable.In the Agreement, Britain and France allowed Germany to annex areas in Czechoslovakia where German-speakers lived.Then, on September 1, 1939, German troops invaded Poland.An example of appeasement was the Munich Agreement of September 1938.Germany agreed not to invade the rest of Czechoslovakia or any other country.In March 1939, Germany broke its promise and invaded the rest of Czechoslovakia.Britain and France immediately declared war on Germany.
