Date world war 2 declared

Answer 1

Hitler never declared war, it was the French and the British that declared war on Germany! Why did they declare war? Because Hitler invaded Poland. Great Britain and France declared war on Germany On September 3, 1939.

Answer 2

In the 1930's, Britain and France had a defence pact with Poland. On 1 September 1939, German forces attacked Poland, so on 3 September 1939, Britain and France declared war on Germany. The United States declared war on Japan on 8 December 1941 following the Japanese attack on Pearl Harbour the previous day. Germany then declared war on the US on 11 December 1941.

Answer 3

According to British historians when Germany invaded Poland on September 2/3, 1939. But the world's most powerful nation wasn't in the war then (America)...so it actually was not a true world war in 1939.

WWII became global (an actual World War) when Pearl Harbor was bombed on December 7, 1941. The US declared war on Japan the following day (since it was Monday)...December 8, 1941.

Therefore, technically (not European history) World Two commenced when America entered the war on December 7/8, 1941.

Japan -- December 8, 1941 Germany, Italy -- December 11, 1941 Bulgaria, Hungary, Romania -- June 5, 1942
