The Pallavicini, Pallavicino, Parravicini and in former times named “Pelavicino”, are an Italian noble family descended from Oberto I (died 1148). The first Pallavicino fief was created by Oberto II, who received it from Frederick Barbarossa in 1162. A number of lines descended from Guglielmo (died 1217), possessor of a series of fiefs between Parma and Piacenza and a descendant of the Lombard Obertenga family (along with the Este, the Cavalcabò and Malaspina). They are:
- The Pallavicini of the Latin Empire
- descendants of Guglielmo through his sons Guy (also known as Galdo) and Rubino
- The Pallavicini of Lombardy
- The Pallavicini of Varano
- The Pallavicini of Polesine
- The Pallavicini of Busseto
- The Pallavicini of Ravarano (today part of Calestano)
- The Pallavicini – Rospigliosi family of Tuscany and Rome
- The Pallavicino of Sicily
A second main branch of the family (or perhaps a separate family) was formed by the descendants of Niccolò Pallavicini (alive in 1154), whose origins are doubtful—probably he belonged to the Genoese patriciate—and whose links with the Obertenghi are uncertain:
- The Pallavicini of Genoa (patricians of Genoa)
The Pallavicinis Mansions
A number of buildings are named after the family:
Palais Pallavicini in Vienna, Austria
Palazzo Pallavicini-Rospigliosi in Rome, Italy
Villa Durazzo-Pallavicini near Genoa, Italy
Palazzo Pallavicini in Bologna, Italy
Villa Gandolfi-Pallavicini in Bologna, Italy
