What were the terms of the Peace of Vienna of 1864?

The Peace of Vienna, signed on October 30, 1864, concluded the German-Danish War. Under the terms of this treaty, the duchies of Schleswig and Holstein were ceded by Denmark to Prussia and Austria as their joint possession.12

This agreement effectively ended Danish authority over the territories, which had been a central point of contention during the conflict. While the treaty established the duchies as the joint property of the two victors, it did not resolve the underlying rivalry between Prussia and Austria regarding the ultimate administration and sovereignty of the region, leading to further political friction that would eventually culminate in the Seven Weeks’ War in 1866.12
