As these old families, "pure Romans of Rome," have died out, their place has been taken by the aristocracy of papal origin, and though as a rule natives of northern provinces, these newcomers have become Roman in sympathies and have inherited the privileges and traditions of the Roman patrician. Not only did each new pope bring his own relatives to Rome in his train and grant them titles, but he also gathered round him followers from his own province among whom he distributed the great papal offices. Sometimes the period of greatness thus bestowed was short-lived, in other cases a permanent aristocracy was created and the papal offices became hereditary. Thus the Ruspoli from father to son are Masters of the Sacred Hospice; the Colonna are Assistant Princes; the Serlupi are Marshals of the Pope's Horse; the Sforza have the hereditary right to appoint the standard-bearer of the Roman people; the Chigi are Marshals of Conclave, replacing the Savelli in this office who had held it for nearly five centuries. Some of these families were nobles in their own province. The Boncompagni were a noble family of Bologna. Coming to Rome with Gregory XIII. in 1572, they were created Dukes of Sora and later Princes of Piombino and of Venosa. [Illustration: MEDIAEVAL HOUSE AT TIVOLI] The Ludovisi were nobles of Pisa, the Borghese patricians of Siena. This great family came to Rome with Paul V. in the early seventeenth century, and was granted princely rank with the title of Sulmona. In the middle of the eighteenth century, Marc' Antonio Borghese married a Salviati heiress and at that period was owner of the beautiful Villa Borghese with its museum and priceless collection of statues, of the great palace by the Tiber, of the villas Mondragone and Aldobrandini at Frascati, and of thirty-six estates in the campagna, building and endowing at the same period the rich Borghese chapel in S. Maria Maggiore. At a later date, Camillo Borghese married Pauline Bonaparte and was appointed governor of Piedmont by Napoleon I. Of late years this family has been almost ruined by reckless building speculations, and the greater portion of their magnificent possessions has been sold and alienated. The Aldobrandini and Salviati are both off-shoots from this family.
