Edward VIII [SEP] Introduction
Additionally, such a marriage would have conflicted with Edward's status as the titular head of the Church of England, which at the time disapproved of remarriage after divorce if a former spouse was still alive. Edward knew the Baldwin government would resign if the marriage went ahead, which could have forced a general election and would have ruined his status as a politically neutral constitutional monarch. When it became apparent he could not marry Wallis and remain on the throne, he abdicated. He was succeeded by his younger brother, George VI. With a reign of 326 days, Edward is one of the shortest-reigning monarchs in British history.
