Prince Carl of Denmark insisted that Norwegians be given a choice on the country's future form of government before he would accept the Storting's offer of the throne. A referendum on 12-13 November 1905 favoured retaining a monarchy, 259,563 votes to 69,264. The Storting formally offered the throne to Carl on 18 November 1905; he accepted, taking the name Haakon VII, becoming Norway's first independent monarch since 1387.[5]
