Chamberlain, Neville

Prime Minister of the United Kingdom from May 1937 - May 1940. In the leadup to World War II, Chamberlain pursued a policy of "appeasement" with Hitler's Germany. He negotiated the Munich Agreement in September 1938, which ceded the German-speaking Sudenland region of Czechoslovakia to Germany in exchange for Hitler's assurances of peace. Chamberlain resigned in 1940, after the outbreak of World War II proved the failure of appeasement. He was succeeded as prime minister by Winston Churchill.
