Final answer:
British policies of appeasement regarding Germany's annexation of Austria were ultimately effective in delaying war for some years.
Step-by-step explanation:
The British policies of appeasement regarding Germany's annexation of Austria were ultimately effective in delaying war for some years. In the hopes of avoiding another war, British and French officials agreed to allow Hitler to take the Sudetenland in Czechoslovakia through the Munich Agreement. This policy of giving up territory in exchange for promises to avoid war became known as appeasement. However, Hitler's actions in March of 1939, when he seized the rest of Czechoslovakia, showed that appeasement had only delayed war and that Hitler still wanted to expand his territory.
