The illegitimate son of pope Alexander VI, Cesare Borgia pursued military campaigns throughout Italy with the aid of his powerful father. After a series of impressive victories, Borgia's power diminished following Alexander's death in 1503. Borgia eventually lost his conquests and died in 1507. During diplomatic missions Machiavelli closely studied Borgia's tactics. Machiavelli praises Borgia's prowess but laments the "malice" of fortune that led to his downfall.
