Pompeo Colonna was an Italian noble, condottiero, politician, and cardinal. At the culmination of his career he was Viceroy of the Kingdom of Naples (1530–1532) for the Emperor Charles V. Born in Rome, he was the son of Girolamo Colonna, whose father Antonio was second Prince of Salerno; and Vittoria Conti, of the Conti de Poli. His family belonged to the highest rank of nobility both of the City of Rome and of the Kingdom of Naples. Pompeo and his family were hereditary supporters of the Holy Roman Empire (Ghibbelines), and they spent their careers fighting their hereditary enemies, the Orsini family, and defending and expanding their family territories and interests. He played a significant, if sometimes disruptive, role in the Conclaves of 1521 and 1523 on behalf of the Imperial interest. His family commitments and his conclave activities brought Pompeo into conflict with the second Medici pope, Clement VII, whose election he vigorously opposed, and made him a leading figure in the attempted overthrow of Pope Clement and the Sack of Rome in 1527.

The 1304–1305 papal conclave was initiated after the death of Pope Benedict XI in July 1304. The conclave took place in Perugia, the city in which Benedict had died, and proved to be a protracted affair. It ran from 10 or 17 July 1304 to 5 June 1305, and ultimately elected the non-cardinal Raymond Bertrand de Got as Pope Clement V. At the time of his election de Got was Archbishop of Bordeaux, and thus a subject of Edward I, King of England, although he was a childhood friend of Philip IV of France. Clement V's decision to relocate the papacy to France was one of the most contested issues in the papal conclave following his 1314 death, during which the minority of Italian cardinals were unable to engineer the return of the papacy to Rome. This immediately preceded the beginning of the Avignon Papacy.
