George VI

His elder brother ascended the throne as Edward VIII after their father died in 1936, but Edward abdicated later that year to marry the twice-divorced American socialite Wallis Simpson. As heir presumptive to Edward VIII, Albert became king, taking the regnal name George VI. In September 1939, the British Empire and most Commonwealth countries—but not Ireland—declared war on Nazi Germany, following the invasion of Poland.

War with the Kingdom of Italy and the Empire of Japan followed in 1940 and 1941, respectively. George VI 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 the independence of India and Pakistan in 1947. George relinquished the title of Emperor of India in June 1948 and instead adopted the new title of Head of the Commonwealth. He was beset by smoking-related health problems in the later years of his reign and died at Sandringham House, aged 56, of a coronary thrombosis. He was succeeded by his elder daughter, Elizabeth II.
