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. Many commentators have viewed that one of the main themes of The Prince is that immoral acts are sometimes necessary to achieve political glory. From Machiavelli's correspondence, a version was apparently being written in 1513, using a Latin title, De Principatibus (Of Principalities).
