The question of the Augustenburg succession made an agreement between the major powers impossible, and on March 31, 1852 the duke of Augustenburg resigned his claim in return for a money payment. Duke Christian sold his rights to the Duchy of Schleswig-Holstein to Denmark in aftermath of Treaty of London, but later renounced his rights to the Duchy of Schleswig-Holstein in favor of his son Frederik August.
