Imperial Circle
The other Ernestine duchies were never members of the Imperial Circle, and did not have the right to vote in the reichstag as the five duchies that the other duchies did (for example, the principalities of Meiningen and Hildburghausen were such; that was one reason why Duke of Saxe-Hildburghausen exchanged his patrimony to that of Altenburg). However they were all autonomous and ultimately, with the dissolution of the Holy Roman Empire on 6 August 1806, that issue became irrelevant.
