In this episode of pplpod, we explore the life of Cesare Borgia, the Renaissance warlord whose rapid rise and fall became the model for ruthless political strategy and a warning about borrowed power. Born in the 1470s as the illegitimate son of Cardinal Rodrigo Borgia, later Pope Alexander VI, he was made a bishop at 15 and a cardinal at 18 through papal nepotism. He studied law at Perugia and Pisa and resented his clerical career while his older brother Giovanni commanded the papal army. Giovanni's murder in 1497, which sources suggest was more likely retaliation for a personal indiscretion than a fratricide, opened the path for Cesare to abandon the church.

The episode follows his unprecedented resignation from the cardinalate on August 17, 1498, and his appointment by Louis XII of France as Duke of Valentinois, earning him the name il Valentino. Backed by papal funds, French cavalry, and Swiss infantry, he conquered the Romagna, using papal bulls to declare local lords illegitimate before his armies arrived, and he hired Leonardo da Vinci as a military engineer in 1502. After the Magione conspiracy of his own mercenary captains, he lured them to Senigallia on New Year's Eve 1502 and had them strangled. In 1503 he and his father both contracted malaria, and Alexander died. Julius II then stripped his lands, Gonzalo Fernandez de Cordoba arrested him in Naples, and he escaped from La Mota to serve Navarre. He died in an ambush at Viana on March 12, 1507, at age 31, leaving a legacy of ambition, cunning, and cautionary borrowed power through Machiavelli's The Prince.
