Orsini-Rosenberg (also Ursin-Rosenberg) is the name of an old Austrian noble family. It originally sprang out from the Graben family (an apparent or illegitimate branch of the House of Meinhardin) from Schloss Alt-Grabenhofen near the city of Graz.
History
The earliest known member of the Orsini-Rosenberg family, Konrad ab dem Roesenperg, lived around 1322. He was a member of the low nobility who lived at Schloss Alt-Grabenhofen, between Reinerkogel and Rosenberg. During the 17th and 18th centuries, the success of the family arose from the steady accumulation of land, and loyalty to the Habsburg Emperor.
On 2 August 1633, Johann Andreas von Rosenberg, Herr von Rosenberg, was elevated to the Reichsfreiherrenstand with the title of Freiherr of the Holy Roman Empire, Freiherr of Lerchenau, Herr of Magereckh and Grafenstein, and in 1648 to the Austrian Grafenstand. Since 1681, the family held the title of Reichsgraf, and in 1683 they became members of the Reichstag. In the same year, they took the name of the old Italian princely Orsini family; their family name changed to Ursini-Rosenberg or Orsini-Rosenberg. On 9 October 1790, Franz Xaver Wolfgang von Orsini-Rosenberg was elevated to Reichsfürst von Orsini-Rosenberg.
