Who served as the British Prime Minister at the start of World War II?

At the start of World War II, Neville Chamberlain held the position of British Prime Minister. He is particularly known for his policy of appeasement towards Adolf Hitler in the lead-up to the war, including the Munich Agreement of 1938, which permitted Germany to annex the Sudetenland region of Czechoslovakia. This approach was initially popular and was intended to maintain peace in Europe, but it ultimately failed when Germany invaded Poland in September 1939, prompting Britain and France to declare war on Germany.

Winston Churchill, who is often associated with the war due to his leadership during its course, actually became Prime Minister only after Chamberlain resigned in May 1940. Clement Attlee and Anthony Eden also served significant roles during and after the war, but their premierships did not coincide with the very beginning of the conflict. Chamberlain's tenure is critical in understanding the British response to early aggression from Nazi Germany and the events that led to the outbreak of the war.
