when did great britain declare war on germany ww2
British and French declaration of war on Germany The Declaration of war by France and the United Kingdom was given on 3 September 1939, after German forces invaded Poland. Despite the speech being the official announcement of both France and the United Kingdom, the speech was given by the British Prime Minister Neville Chamberlain, in Westminster, London.[1]
British Empire in World War II When the United Kingdom declared war on Nazi Germany at the outset of World War II it controlled to varying degrees numerous crown colonies, protectorates and the Indian Empire. It also maintained unique political ties to four semi-independent Dominions—Australia, Canada, South Africa, and New Zealand[1]—as part of the Commonwealth.[2] In 1939 the British Commonwealth was a global superpower, with direct or de facto political and economic control of 25% of the world's population, and 30% of its land mass.
