George VI [SEP] Introduction
In September 1939, the British Empire and Commonwealth—except Ireland—declared war on Nazi Germany. War with the Kingdom of Italy and the Empire of Japan followed in 1940 and 1941, respectively. George was seen as sharing the hardships of the common people and his popularity soared. Buckingham Palace was bombed during the Blitz while the King and Queen were there, and his younger brother, the Duke of Kent, was killed on active service. George became known as a symbol of British determination to win the war. Britain and its allies were victorious in 1945, but the British Empire declined. Ireland had largely broken away, followed by independence of India and Pakistan in 1947.
