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 list of Imperial Circle Estate members at the same time can be found at
Imperial Circle Estates. A full list of every state belonging to the Holy Roman Empire at any time would be an impossible project.
