Diaconate of Cesare Borgia as
Duke of Valentinois and
Duke of Romagna and
Captain-General of the Church. Cesare was initially groomed for a career in the
Roman Catholic Church. Following school in
Perugia and
Pisa, Cesare studied law at the
Studium Urbis (today as the
Sapienza University of Rome). He was made Bishop of
Archdiocese of Pamplona and Tudela (aged 15) and Archbishop of
Valencia (aged 17). In 1493, he had also been appointed bishop of both
Castres and
Elne. In 1494, he also received the title of abbot of the
abbey of Saint-Michel-de-Cuxa. Along with his father's elevation to Pope, Cesare was made
Cardinal at the age of 18. as Giovanni's disappearance could finally open to him a long-awaited military career and also solve the jealousy over
Sancha of Aragon, wife of Cesare's younger brother,
Gioffre, and mistress of both Cesare and Giovanni. Cesare's role in the act has never been clear. However, he had no definitive motive, as he was likely to be given a powerful secular position, whether or not his brother lived. It is possible that Giovanni was killed as a result of a sexual liaison. On 17 August 1498, Cesare resigned from the cardinalate in order to pursue a military career. On the same day,
Louis XII named Cesare
Duke of Valentinois. This random title was selected as being homophonous with his nickname
Il Valentino ("The
Valencian"), derived from his father's papal epithet in Latin
Valentinus ("The
Valencian") indicating his birth in Xàtiva in the
Kingdom of Valencia under the
Crown of Aragon, and along with Cesare's former position as Cardinal of Valencia. On 6 September 1499, he was released from all ecclesiastical duties and
laicised from his diaconal orders (because he only was ordained deacon on 26 March 1494 and never received other major orders as
priesthood and
bishop consecration).
Military Cesare's career was founded upon his father's ability to distribute patronage, along with his alliance with France (reinforced by his marriage with
Charlotte d'Albret, sister of
John III of Navarre), in the course of the
Italian Wars. Louis XII invaded Italy in 1499; after
Gian Giacomo Trivulzio had ousted its duke
Ludovico Sforza, Cesare accompanied the king in his entrance into
Milan. At this point, Alexander decided to profit from the favourable situation and carve out for Cesare a state of his own in northern Italy. To this end, he declared that all his vicars in
Romagna and
Marche were deposed. Though in theory subject directly to the pope, these rulers had been practically independent or dependent on other states for generations. In the view of the citizens, these vicars were cruel and petty. When Cesare eventually took power, he was viewed by the citizens as a great improvement. Cesare was appointed commander of the papal armies with a number of Italian mercenaries, supported by 300 cavalry and 4,000 Swiss infantry sent by the king of France. Alexander sent him to capture
Imola and
Forlì, ruled by
Caterina Sforza (mother of the Medici
condottiero Giovanni dalle Bande Nere). Despite being deprived of his French troops after the conquest of those two cities, Borgia returned to Rome to celebrate a triumph and to receive the title of
Papal Gonfalonier from his father. In 1500, the creation of twelve new cardinals granted Alexander enough money for Cesare to hire the
condottieri, Vitellozzo Vitelli,
Gian Paolo Baglioni,
Giulio and
Paolo Orsini, and
Oliverotto Euffreducci, who resumed his campaign in Romagna.
Giovanni Sforza, first husband of Cesare's sister
Lucrezia, was soon ousted from
Pesaro;
Pandolfo Malatesta lost
Rimini;
Faenza surrendered, its young lord
Astorre III Manfredi being later drowned in the
Tiber by Cesare's order. In May 1501, the latter was created Duke of Romagna. Hired by Florence, Cesare subsequently added the lordship of
Piombino to his new lands. While his
condottieri took over the siege of Piombino which ended in 1502, Cesare commanded the French troops in the sieges of Naples and
Capua, defended by
Prospero and
Fabrizio Colonna. On 24 June 1501, Borgia's troops stormed the latter to end the siege of Capua. In June 1502, he set out for Marche, where he was able to capture
Urbino and
Camerino by treason. He planned to conquer
Bologna next. However, his
condottieri, most notably Vitellozzo Vitelli and the Orsini brothers (Giulio, Paolo, and Francesco), feared Cesare's cruelty and set up a
plot against him.
Guidobaldo da Montefeltro and
Giovanni Maria da Varano returned to Urbino and Camerino, and
Fossombrone revolted. The fact that his subjects had enjoyed his rule thus far meant that his opponents had to work much harder than they would have liked. He eventually recalled his loyal generals to Imola, where he waited for his opponents' loose alliance to collapse. On December 31, 1502, Cesare called for a reconciliation, but imprisoned his
condottieri in
Senigallia, then called Sinigaglia, a feat described as a "wonderful deceiving" by historian
Paolo Giovio,
and had them strangled. In 1503, he conquered the
Republic of San Marino. ==Later years and death==
