Chamberlain War Ministry

The Chamberlain War Ministry was formed on 3 September 1939 by Neville Chamberlain, Prime Minister of the United Kingdom, who reconstructed his existing government so as to prosecute the Second World War.

The government was notable for having a small War Cabinet consisting of only the principal and service ministers, with most other government positions serving outside the Cabinet.

The government ended on 10 May 1940 when Chamberlain resigned and was succeeded by Winston Churchill who formed the Churchill Coalition.
