The Danish Unitary State (Danish: Helstaten; German: Gesammtstaat) was a Danish political designation for the monarchical state formation of Denmark, Schleswig, Holstein, and Saxe-Lauenburg, between the two treaties of Vienna in 1815 and 1864. The usage of the term became relevant after the First Schleswig War, when a need for a constitutional framework for the monarchy was present, which ought to follow the premises of the London Protocol, which prohibited a closer connection between two of the monarchy's possessions. The political designation was ultimately eliminated after The Second Schleswig War and was replaced by the national state in 1866.
