The House of Savelli (de Sabellis in documents) were a rich and influential Roman aristocratic family who rose to prominence in the 13th century, and which included several popes, senators and condottieri.

The family, who held the lordship of Palombara Sabina, took their name from the rocca (castle) of Sabellum,[2] near Albano, which had belonged to the counts of Tusculum before it passed to the Savelli.

Luca's decision to side with Emperor Frederick II against Honorius III's successor, Gregory, brought various material benefits to the family, including some fiefs in the Sabina region.

Castel Gandolfo had been relinquished under terms of Pope Clement VIII's "bull of the barons" to the Papal treasury in return for a mere 150,000 scudi in 1596, and in 1650 Albano, with its princely title, was turned over to the Savalli family.

Members of this line included the republican patriot Luigi Giannuzzi Savelli of the Princes of Cerenzia who was shot 3 April 1799 by orders of Cardinal Ruffo.
