Elizabeth was born in Mayfair, London, as the first child of the Duke and Duchess of York (later King George VI and Queen Elizabeth). Her father ascended the throne on the abdication of his brother King Edward VIII in 1936, from which time she was the heir presumptive. She was educated privately at home and began to undertake public duties during the Second World War, serving in the Auxiliary Territorial Service. In 1947, she married Philip, Duke of Edinburgh, a former prince of Greece and Denmark, with whom she had four children: Charles, Prince of Wales; Anne, Princess Royal; Prince Andrew, Duke of York; and Prince Edward, Earl of Wessex.
