The Prince (Italian: Il Principe [il ˈprintʃipe]; Latin: De Principatibus) is a 16th-century political treatise written by Italian diplomat and political theorist Niccolò Machiavelli as an instruction guide for new princes and royals. The general theme of The Prince is of accepting that the aims of princes – such as glory and survival – can justify the use of immoral means to achieve those ends. The Prince is sometimes claimed to be one of the first works of modern philosophy, especially modern political philosophy, in which the "effectual" truth is taken to be more important than any abstract ideal. It is also notable for being in direct conflict with the dominant Catholic and scholastic doctrines of the time, particularly those concerning politics and ethics. Although it is relatively short, the treatise is the most remembered of Machiavelli's works, and the one most responsible for bringing the word "Machiavellian" into usage as a pejorative. It even contributed to the modern negative connotations of the words politics and politician in Western countries. In subject matter, it overlaps with the much longer Discourses on Livy, which was written a few years later. In its use of near-contemporary Italians as examples of people who perpetrated criminal deeds for politics, another lesser-known work by Machiavelli to which The Prince has been compared is the Life of Castruccio Castracani.
