Appeasement is a diplomatic strategy where one party concedes to the demands of another to maintain peace and avoid conflict. This approach is often used when a country or leader seeks to prevent war or aggression by making compromises, even if it means sacrificing some of their own interests. Historically, appeasement is most commonly associated with the actions of European leaders in the 1930s, particularly regarding Adolf Hitler and Nazi Germany. They believed that by allowing Hitler to expand his territory, they could prevent a larger conflict, but this ultimately failed and contributed to the outbreak of World War II.
