Appeasement

Appeasement in a political context is a diplomatic policy of making political or material concessions to an enemy power in order to avoid conflict.

The term is most often applied to the foreign policy of the British Prime Ministers Ramsay Macdonald, Stanley Baldwin and Neville Chamberlain towards Nazi Germany and Hitler and Fascist Italy between 1935 and 1939.

Their policies have been the subject of intense debate for more than seventy years among academics, politicians and diplomats. The historians' assessments have ranged from condemnation for allowing Adolf Hitler's Germany to grow too strong, to the judgment that they had no alternative and acted in their country's best interests. At the time, these concessions were widely seen as positive, and the Munich Pact concluded on 30 September 1938 among Germany, Britain, France, and Italy prompted Chamberlain to announce that he had secured "peace for our time."

Chamberlain's policy of appeasement emerged from the failure of the League of Nations and the failure of collective security. The League of Nations was set up in the aftermath of World War I in the hope that international cooperation and collective resistance to aggression might prevent another war. Members of the League were entitled to the assistance of other members if they came under attack. The policy of collective security ran in parallel with measures to achieve international disarmament and where possible was to be based on economic sanctions against an aggressor. It appeared to be ineffectual when confronted by the aggression of dictators, notably Germany's Remilitarization of the Rhineland, and Italian leader Benito Mussolini's invasion of Abyssinia.
