The wedding of Prince Edward, Duke of Windsor, and Wallis Simpson took place on Thursday 3 June 1937 at Château de Candé in France.

The bride was a twice-divorced American socialite whose relationship with the groom, formerly King Edward VIII, caused a constitutional crisis which led to his abdication in December 1936.

The next day, he broke royal protocol by watching the proclamation of his accession from a window of St James's Palace, in the company of the still-married Wallis.

She decided to flee the country as the scandal broke, and was driven to the south of France where she stayed at the Villa Lou Viei, near Cannes, the home of her close friends Herman and Katherine Rogers.

On December 11, Edward said in a radio broadcast, "I have found it impossible to carry the heavy burden of responsibility, and to discharge my duties as King as I would wish to do, without the help and support of the woman I love.

"[6] Edward left Britain for Austria, where he stayed at Schloss Enzesfeld, the home of Baron Eugène and Baroness Kitty de Rothschild.

However, letters patent, issued by the new king and unanimously supported by the Dominion governments, prevented Wallis, now Duchess of Windsor, from sharing her husband's style of "Royal Highness".
