The Wars of German Unification

The Wars of German Unification were a series of three conflicts from 1864 to 1871 that led to the unification of the German status under the leadership of Prussia and the consequent formation of the German Empire. These conflicts include (1) The Second Schleswig War (1864) and (2) The Austro-Prussian War (1866).

The Second Schleswig War

1864 1864

After the First Schleswig War, as per the London Protocol, Denmark gained control over the duchies of Schleswig and Holstein. However, they did not become part of the Danish monarchy. Holstein was, however, part of the German Confederation, while Schleswig was not. These complex historical ties and differing national affiliations led to tensions and, ultimately, to a Second Schleswig War between the Kingdom of Denmark and the combined forces of the German Confederation.

    The Invasion of Schleswig
    Military: Battle

    January 16, 1864

    The Duchy of Holstein was a part of the German Confederation, while Schleswig was not. Denmark and Germany were fighting for control over these two duchies. Although the London Protocol of 1852 had tried to resolve the status of the duchies in relation to Denmark, there were continuous tensions between Denmark and Germany. In 1863, Denmark tried to integrate Schleswig more closely, violating the agreements in the London Protocol. Prussia and Austria, both seeking influence in the German Confederation and beyond, responded to this action by giving an ultimatum. Denmark rejected the ultimatum, leading to the invasion of Schleswig by Prussian and Austrian forces in early 1864.
