Austro-Prussian War

The Austro-Prussian War (14 June-22 July 1866) was a conflict the Prussian-led German Confederation states and Italy won against the Austrian-led German Confederation states. The reason for the war was the Austrian attempts to increase their regional influence in jointly occupied (with Prussia) Schleswig-Holstein. As the aftermath of the war; Prussia annexed many of Austria’s former allies and formed the North German Confederation, and the Austrian Empire was transformed via the Austro-Hungarian Compromise of 1867 into the dual monarchy of Austria-Hungary rather than the Habsburg rule. The importance of the conflict is that it is a big step towards German unification.
