On the 11th December 1936, King Edward VIII of the United Kingdom announced his abdication in a worldwide radio broadcast. He had signed the Instruments of Abdication on the 10th, but it only became official when he gave royal assent to His Majesty’s Declaration of Abdication Act 1936 after it was passed by Parliament the next day.
Edward abdicated in order to marry American divorcee Wallis Simpson. Simpson had divorced her first husband in 1927, and was married to a second when her relationship with the then Prince of Wales began. Edward was in a serious relationship with Wallis when he became king following the death of his father on the 20th January 1936, but as the head of the Church of England faced a crisis since divorced people were forbidden from remarrying if their ex-spouses were still alive, as was the case with Wallis.
Wallis Simpson filed for divorce from her second husband in October 1936, which led to speculation in the American press that marriage to Edward was imminent. Although the British press remained silent on the matter, he was warned that this wouldn’t be the case for much longer and that he needed to address the issue. In the middle of November Edward told Stanley Baldwin, the British Prime Minister, of his intention to marry Wallis. Baldwin gave the King three options: give up the idea of marriage; marry against his ministers’ wishes; or abdicate. He chose the latter.
Less than a month later his younger brother was proclaimed King George VI while Edward became Duke of Windsor. He married Wallis on the 3rd June 1937.
