Passage: The union amendments were revoked after the dissolution of the ninety-one-year-old union in 1905. The question of a King was again considered, and the Storting elected to offer the throne to the 33-year-old Prince Carl of Denmark, married to Princess Maud of Wales, the daughter of King Edward VII of the United Kingdom. By bringing in a king with British royal ties, it was hoped that Norway could court Britain's support. Prince Carl was however well aware of a surge of republicanism in Norway and of the constitutional situation of the Norwegian throne. He insisted that he would accept the crown only if the Norwegian people expressed their will for monarchy by referendum and if the parliament then elected him king. On 13 November, the Norwegian votes decided on monarchy with a 74 percent majority, and Carl was elected King by the Storting, taking the name and title Haakon VII, Norway's King.
