The Salm-Mörchingen family lost the titles of "Wildgrave of Dhaun" and "Rhinegrave of Stein" in 1681, when they lacked a male successor. Salm-Kyrburg was from then on run by regents on their behalf. Philip Joseph reigned with his brother John from 1716. When Salm-Kyrburg again arose, this time as a principality, Philip Joseph became its first prince.
