Neville Chamberlain, English businessman and politician, Prime Minister of the United Kingdom (died 1940)

Arthur Neville Chamberlain was a British politician who served as Prime Minister of the United Kingdom from May 1937 to May 1940 and Leader of the Conservative Party from May 1937 to October 1940. He is best known for his foreign policy of appeasement, and in particular for his signing of the Munich Agreement on 30 September 1938, ceding the German-speaking Sudetenland region of Czechoslovakia to Nazi Germany led by Adolf Hitler. Following the invasion of Poland on 1 September 1939, which marked the beginning of World War II, Chamberlain announced the declaration of war on Germany two days later and led the United Kingdom through the first eight months of the war until his resignation as prime minister on 10 May 1940.

The prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet, and selects its ministers. Modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, so they are invariably members of Parliament.
