ORSINI: The Orsini family is a prominent Italian noble lineage, influential in medieval Italy and Renaissance Rome. Founded around 600 A.D. by Cajo Orso Orsini, the family produced five popes, including Celestine III and Benedict XIII, and numerous cardinals. They were key supporters of the papacy against rival families like the Colonnas, shaping Roman politics for centuries. Currently, the family is represented by Domenico Napoleone Orsini, Duke of Gravina, with historical ties to various territories in Italy and a legacy of military and ecclesiastical leadership.
