Late 15th-century Italian nobleman and Catholic cardinal
Cesare Borgia (13 September 1475 – 12 March 1507) was an Italian cardinal and condottiero (mercenary leader), an illegitimate son of Pope Alexander VI and member of the Spanish-Aragonese House of Borgia. His fight for power was a major inspiration for The Prince by Niccolò Machiavelli. After initially entering the Church and becoming a cardinal on his father's election to the papacy, he resigned after the death of his brother in 1498. He served as a condottiero for King Louis XII of France around 1500, and occupied Milan and Naples during the Italian Wars.
