German Confederation
Territorial legacy

The current countries whose territory were partly or entirely located inside the boundaries of the German Confederation 1815–1866 are:

Denmark proper has never been a member state, but its king was at the same time the duke of the member states Holstein and Lauenburg. The Duchy of Schleswig (which nowadays partially belongs to Denmark) was never a part of the Confederation although it was mentioned in the 1849 Frankfurt Constitution and governed briefly by a government installed by the German Central Government. However, Holstein, Lauenburg and Schleswig were combined under an Austrian-Prussian condominium in 1864–1866.
