King of Denmark

Background

This difference caused problems when Frederick VII of Denmark proved childless, making a change in dynasty imminent, and causing the lines of succession for the duchies on one hand and for Denmark on the other to diverge. That meant that the new King of Denmark would not also be the new Duke of Schleswig or Duke of Holstein. To ensure the continued adhesion of the Elbe duchies to the Danish Crown, the line of succession to the duchies was modified in the London Protocol of 1852, which designated Prince Christian IX of Schleswig-Holstein-Sonderburg-Glücksburg, as the new heir apparent, although he was, strictly, the heir neither to the Crown of Denmark nor to the Duchies of Schleswig, Holstein or Lauenburg by primogeniture. Originally, the Danish prime minister Christian Albrecht Bluhme wanted to keep the separate hereditary principles, but in the end the government decided on a uniform agnatic primogeniture, which was accepted by the Parliament.
