List of states in the Holy Roman Empire
This is a list of states, which were part of the Holy Roman Empire at any time within its existence between 962 and 1806.
Warning: The list is extremely incomplete. A full list of members of the Reichstag as of 1792 can be found here: List of Reichstag participants (1792). A full list of every state belonging to the Holy Roman Empire at any time would be an impossible project.
