Francesco Maria del Monte, full name Francesco Maria Bourbon del Monte Santa Maria, (5 July 1549 – 27 August 1627) was an Italian Cardinal, diplomat and connoisseur of the arts. His fame today rests on his early patronage of the important Baroque master Caravaggio, and on his art collection (the del Monte collection) which provides provenance for many important works of the period.
Born in Venice of the aristocratic del Monte family of Tuscan origin (which provided several cardinals to the Church), he was the son of Marquis Ranieri Bourbon del Monte, first count of Monte Baroccio, and Minerva Pianosa. He began his ecclesiastical career as Abbot commendatario of Santa Croce a Monte Fabali. He then went to Rome when he was still quite young, and was appointed as auditor for Cardinal Alessandro Sforza, before being finally admitted into the court of Cardinal Ferdinando de' Medici. He made his way up through the clerical ranks as Referendary of the Tribunals of the Apostolic Signature of Justice and of Grace (1580), and later went to serve the grand-duke of Tuscany, the former Cardinal Ferdinando de' Medici.
He was created cardinal deacon in the consistory of 14 December 1588 under Pope Sixtus V, and received the deaconry of S. Maria in Domnica the following year. He took part in the two conclaves of 1590 (Papal Conclave of September 1590 and the Papal Conclave of Autumn 1590), the conclave of 1591 and the conclave of 1592. He subsequently took the titles of Santa Maria in Aracoeli, Santa Maria in Trastevere, and S. Lorenzo in Lucina. As a cardinal he proved an accomplished diplomat and administrator: he represented the interests of the Grand Duke of Tuscany, the former Cardinal Ferdinando de' Medici, in Rome, and was firmly but discreetly pro-French in the ongoing struggle between the French and Spanish for influence over the papacy.
