Principality of Salm
The Rhinegraves began to call themselves Counts of Salm too, they were raised to princes in 1623. Their line included several cadet branches ruling over minor principalities such as Salm-Salm, Salm-Horstmar, and Salm-Kyrburg. In the German Mediatisation of 1803, the Princes of Salm-Salm and Salm-Kyrburg received the southwestern estates of the former Prince-Bishopric of Münster with the Lordship of Anholt and ruled the newly established Principality of Salm jointly as a condominium.
