The Battle of Britain was a military campaign of the Second World War, when the Royal Air Force (RAF) defended the United Kingdom against the German Air Force (Luftwaffe) attacks from the end of June 1940. It is described as the first major campaign fought entirely by air forces. The British officially recognise its duration as from 10 July until 31 October 1940, which overlaps with the period of large-scale night attacks known as the Blitz, while German historians do not accept this subdivision and regard it as a campaign lasting from July 1940 to June 1941.

The Battle of Britain takes its name from a speech by Winston Churchill to the House of Commons on 18 June: "What General Weygand has called The Battle of France is over. The battle of Britain is about to begin."
