Edward VIII (Edward Albert Christian George Andrew Patrick David; 23 June 1894 – 28 May 1972), later known as the Duke of Windsor, was King of the United Kingdom and the Dominions of the British Empire and Emperor of India from 20 January 1936 until his abdication in December of the same year.

Wallis, Duchess of Windsor (born Bessie Wallis Warfield, later Simpson; June 19, 1896 – April 24, 1986), was an American socialite and wife of the former King Edward VIII. Their intention to marry and her status as a divorcée caused a constitutional crisis that led to Edward's abdication.
