Wallis, Duchess of Windsor (previously Wallis Simpson, Wallis Spencer, and Wallis Warfield; 19 June 1896 – 24 April 1986) was an American socialite. Her third husband, Prince Edward, Duke of Windsor, formerly King Edward VIII, abdicated his throne to marry her. The King's desire to marry a woman who had two living ex-husbands threatened to cause a constitutional crisis in the United Kingdom and the Dominions, and ultimately led to his abdication in December 1936 to marry "the woman I love". After the abdication, the former king was created Duke of Windsor by his brother and successor, King George VI. Edward married Wallis six months later, after which she was formally known as the Duchess of Windsor, without the style "Her Royal Highness". She was instead styled as "Her Grace", a style normally reserved only for non-royal dukes and duchesses.
