House of Leyen


The house von der Leyen is an ancient German noble family of princely and historically sovereign rank.
As a former ruling and mediatized family, it belongs to the Hochadel.

History

The origin can be traced to the middle of the 10th century, which had estates on the Moselle. Originally the family was named de Petra or by its castle in Gondorf. Since the 14th century it has called itself von der Leyen. Its members had the hereditary office of sénéchal in the Electorate of Trier. They also had Adendorf near Bonn, Leiningen on the Hunsrück, the Lordship of Arenfels and St. Ingbert.
Prior to 1660, Hugo Ernst became Lord of Blieskastel and, in 1657, was created Reichsfreiherr von der Leyen. In addition to its scattered territories the family acquired the lordships of Burresheim and Blieskastel before 1660, where it built a residence around 1760. In 1697 Freiherr Karl Caspar received the county of Hohengeroldseck as a fiefdom from Austria. In 1711 he was created Imperial count von der Leyen und zu Hohengeroldseck. With most of the count's territories lost to Napoleon France, Reichsgraf Philipp Franz still retained the county Geroldseck. Upon joining the Rheinbund in 1806, he was created Fürst von der Leyen. His mother's brother was Karl Theodor Anton Maria von Dalberg, who later became Prince-Primate of the Confederation of the Rhine and Grand Duke of Frankfurt. In 1819 the principality's holdings were mediatized under Baden, although the title is still being nominally held by House von der Leyen.
Two members of the family became Archbishop of Trier:
and one Archbishop of Mainz:
Erwein Otto Philipp Prince von der Leyen, died without male issue, but left his title and property to his grandson, Philipp-Erwein IV von Freyberg zu Eisenberg, 7th Prince von der Leyen und zu Hohengeroldseck. He will be succeeded by Wolfram, Hereditary Prince of Leyen and zu Hohengeroldseck. Prince Philipp-Erwein IV the current head of the family is descended, amongst others, from Frederick II, Holy Roman Emperor, Vsevolod I of Kiev, Hugh Capet, Eric the Victorious, Harold Godwinson, Pope Julius II and Pope Paul III.
The members of the House of Leyen are entitled a formal style of Address using the predicate Serene Highness. Although German law no longer acknowledges or recognizes a status for noble houses or their titles per se, the government does allow for titles to be used in lieu of a surname.
