The conclave began on May 8. The cardinals were those of the March conclave, with the exception of Cardinal Agucci (who died on April 27, since Leo XI had created no new cardinals. Of the sixty-seven cardinals, sixty-two participated in the final election. There were two principal parties, headed by Cardinal Pietro Aldobrandini (nephew of Clement VIII) and Cardinal Andrea Peretti Montalto. At the beginning of the conclave, a number of electors were leaning towards Cardinal Domenico Toschi, the Bishop of Tivoli, an experienced soldier, lawyer and administrator, who had been governor of Rome from 1595 to 1599. He was, however, spoken against, more for his manners and his style of speaking than his competence (It may have been simple class prejudice), Cardinal Baronius remarked that this did not suit a Vicar of Christ, and most of Toschi's supporters transferred their votes to (of all people) Baronius himself (to a total of 32).
Cardinal Montalto had been showing a preference for Cardinal Camillo Borghese. The French cardinals had not yet chosen their own candidate, but, putting their trust in Montalto's judgment, turned their support to Borghese as well.
On the evening of May 16, Cardinal Camillo Borghese, Vicar General of Rome and head of the Holy Inquisition, was elected pope by acclamation. He was 53 years of age.
Paul V was crowned in the Vatican Basilica on May 29. He took possession of the Lateran Basilica on November 6.
