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. As a remarkable general theme, The Prince appears to take it for granted that immoral acts are justified if they can help achieve political glory. From Machiavelli's correspondence, a version was apparently being written in 1513, using a Latin title, De Principatibus (Of Principalities).
