In early December 1936, a constitutional crisis in the British Empire arose when King Edward VIII proposed to marry Wallis Simpson, an American socialite who was divorced from her first husband and was in the process of divorcing her second.
The marriage was opposed by the governments of the United Kingdom and the Dominions of the British Commonwealth. Religious, legal, political, and moral objections were raised. As the British monarch, Edward was the nominal head of the Church of England, which at this time did not allow divorced people to remarry in church if their ex-spouses were still alive. For this reason, it was widely believed that Edward could not marry Simpson and remain on the throne. As a twice-divorced woman, Simpson was perceived to be politically, morally and socially unsuitable as a prospective queen consort. It was widely assumed by the Establishment that she was driven by love of money or position rather than love for the King. Despite the opposition, Edward declared that he loved Simpson and intended to marry her as soon as her second divorce was finalised.
The widespread unwillingness to accept Simpson as the King's consort and Edward's refusal to give her up led to his abdication in December 1936. He was succeeded by his brother Albert, who became George VI. Edward was given the title of Duke of Windsor, and styled Royal Highness, following his abdication, and he married Simpson the following year. They remained married until his death 35 years later.
Edward had been introduced to Wallis Simpson, an American citizen and wife of British shipping executive Ernest Aldrich Simpson, by Lady Furness on 10 January 1931, when Edward was Prince of Wales. Ernest Simpson was Wallis's second husband; her first marriage, to U.S. Navy pilot Win Spencer, had ended in divorce in 1927. It is generally accepted that Wallis Simpson and Edward became lovers in 1934, while Lady Furness (who was also in a relationship with the prince) was visiting relatives in the United States.
