Britain and France adopted a policy of appeasement when meeting with Hitler at the Munich Conference because they were seeking to avoid another devastating war like World War I. They believed that by giving in to some of Hitler's demands, such as allowing him to annex the Sudetenland in Czechoslovakia, they could prevent further conflict and maintain peace in Europe. Additionally, many in Britain and France were still recovering from the trauma of World War I and were hesitant to confront Hitler militarily without clear support from other powers. They also hoped that by appeasing Hitler, they could buy time to strengthen their own military capabilities and form alliances with other countries to better prepare for a potential conflict in the future.
