Late 15th-century Italian nobleman and Catholic cardinal
Cesare Borgia (13 September 1475 – 12 March 1507) was a Roman Catholic deacon—cardinal and later an Italian condottiero (mercenary). He was the illegitimate son of Pope Alexander VI of the Aragonese House of Borgia and was a sibling to Lucrezia Borgia. After initially entering the Church and becoming a cardinal on his father's election to the papacy, he resigned his diaconal profession after the death of his brother in 1498. He was employed as a condottiero for King Louis XII of France around 1500, and occupied both Milan and Naples during the Italian Wars.
