The Savelli (de Sabellis in documents) were a rich and influential Roman aristocratic family who rose to prominence in the 13th century and became extinct in the main line with Giulio Savelli (1626—1712). They provided at least one pope: Giacomo Savelli, Honorius IV (1285–1287). His father, Luca Savelli, was a Roman senator and sacked the Lateran in 1234. Luca's decision to side for Emperor Frederick II against Honorius III's successor, Gregory, gained the family large possessions in the Lazio. Honorius' brother, Pandolfo Savelli, was the podestà of Viterbo in 1275.
