19 h 53 min, 26 févr. 1865 ans - Convention of Gastein

Description:

Vienna would have liked to see Schleswig-Holstein become an independent secondary state in the German Confederation. Berlin, on the other hand, hoped for the outright annexation of the duchies or at least the indirect control of their government. In 1865 their differences were papered over by the Convention of Gastein, which placed Schleswig under Prussian and Holstein under Austrian administration but which also reaffirmed the joint sovereignty of the two governments over the duchies.
