The Discourses on Livy is a work of political history and philosophy composed in the early 16th century by the famed Florentine public servant and political theorist Niccolò Machiavelli (1469-1527), best known as the author of The Prince. Where The Prince is devoted to advising the ruler of a principality, i.e., a type of monarchy, the Discourses purport to explain the structure and benefits of a republic, a form of government based on popular consent and control. It is considered almost unanimously by scholars to be if not the first, then certainly the most important, work on republicanism in the early modern period.
