Edward VIII (Edward Albert Christian George Andrew Patrick David Windsor; later The Prince Edward, Duke of Windsor; 23 June 1894 – 28 May 1972) was King of the United Kingdom and the British Dominions beyond the Seas, and Emperor of India from the death of his father, George V (1910–36), on 20 January 1936 until his abdication on 11 December 1936. He was the second British monarch of the House of Windsor, his father having changed the name of the Royal house from the Saxe-Coburg-Gotha in 1917.
Prior to his accession to the throne, Edward VIII held the titles of Prince Edward of York, Prince Edward of York and Cornwall, Duke of Cornwall, Duke of Rothesay, and Prince of Wales (all with the style Royal Highness). After his abdication he reverted to the style of a son of the sovereign, The Prince Edward, and was created Duke of Windsor on 8 March 1937. During World War II (1939–45) he was the Governor and Commander-in-Chief of the Bahamas.
Edward VIII is the only British monarch to have voluntarily relinquished the throne. He signed the instrument of abdication on 10 December 1936. The British Parliament passed His Majesty's Declaration of Abdication Act 1936 the next day and, on its receiving Royal Assent from Edward VIII, he legally ceased to be King in all but one of his realms. His abdication as King of Ireland occurred one day later. After Lady Jane Grey and Edward V, he is the third shortest-reigning monarch in British history, and the three are the only British monarchs never to have been crowned.
