What was appeasement in the 1930 who practiced it?

Appeasement in the 1930s refers to the policy adopted primarily by Britain and France of conceding to the aggressive demands of Nazi Germany, aiming to maintain peace in Europe and avoid another large-scale conflict. The most notable instance was the Munich Agreement of 1938, where these powers allowed Hitler to annex the Sudetenland in Czechoslovakia without military intervention. This policy ultimately failed, as it emboldened Germany and contributed to the outbreak of World War II.
