The Prince (Italian: Il Principe [il ˈprintʃipe]; Latin: De Principatibus) is a 16th-century political treatise written by the Italian diplomat, philosopher, and political theorist Niccolò Machiavelli in the form of a realistic instruction guide for new princes. The Prince shocked many readers by assuming that immoral acts are justifiable if they achieve political glory. From Machiavelli's correspondence, a version was apparently being written in 1513, using a Latin title, De Principatibus (Of Principalities).
