The Prince is a 16th-century political treatise by the Italian diplomat and political theoristNiccolò Machiavelli. From correspondence a version appears to have been distributed in 1513, using a Latin title, De Principatibus (Of Principalities). However, the printed version was not published until 1532, five years after Machiavelli's death.
Although it was written as if it were a traditional work in the mirrors for princes style, it is generally agreed that it was especially innovative. This is only partly because it was written in the vernacular Italian rather than Latin, a practice which had become increasingly popular since the publication of Dante's Divine Comedy and other works of Renaissance literature. The Prince is sometimes claimed to be one of the first works of modern philosophy, especially modern political philosophy, in which the effective truth is taken to be more important than any abstract ideal. It was also in direct conflict with the dominant Catholic and scholastic doctrines of the time concerning politics and ethics.

Niccolò di Bernardo dei Machiavelli (3 May 1469 - 21 June 1527) was an Italian diplomat, politician, historian, philosopher, humanist, and writer of the Renaissance period. He has often been called the father of modern political science. He was for many years a senior official in the Florentine Republic, with responsibilities in diplomatic and military affairs. He also wrote comedies, carnival songs, and poetry. His personal correspondence is renowned in the Italian language. He was secretary to the Second Chancery of the Republic of Florence from 1498 to 1512, when the Medici were out of power. He wrote his most renowned work The Prince (Il Principe) in 1513.
