In the German-Danish War of 1864, Denmark fought against the allied forces of Prussia and Austria.12
The conflict arose from the Schleswig-Holstein question, specifically regarding the status of the duchies of Schleswig and Holstein following Denmark's attempt to integrate Schleswig into the Danish state in 1863. Although both Prussia and Austria were members of the German Confederation, they acted independently of the broader confederation to pursue their own strategic interests in the region. The war concluded with the Treaty of Vienna, which resulted in the duchies becoming the joint possession of Prussia and Austria.321
