The Duke of Windsor became King Edward VIII on 20 January 1936, following the death of his father, George V. His Nazi sympathies were well known, and although he did not visit Hitler during the time he was on the throne, nevertheless he sent a personal message suggesting a peace agreement between Germany and England.

His relationship with Wallis Simpson, an American divorcee, is thought by many to have been the saving of Britain from an unholy alliance with the Nazi regime, although once he had abdicated the throne in order to marry her he did what he could to broker peace with Germany.

In an interview with journalist Fulton Oursler in 1940, he said, “Tell Mr ­Roosevelt that if he will make an offer of intervention for peace, that before anyone in England can oppose it, the Duke of Windsor will instantly issue a statement supporting it and that will start a revolution in England and force peace.” ("The Nazi King" by Simon Edge, The Daily Express, 11 July 2009)
