Frederick VII of Denmark
Much of the dispute focused on the heir of King Frederick VII of Denmark. The Germans of Holstein and Schleswig supported the House of Augustenburg, a cadet branch of the Danish royal family, but the average Dane considered them too German and preferred the rival Glücksburg branch with Prince Christian of Glücksburg as the new sovereign. Prince Christian had served on the Danish side in the First Schleswig War (1848–1851).
