The prince

“All satates, all powers, that have held and hold rule over men have been and are either republics or principalities...”
The Prince is a 16th-century political treatise by the Italian diplomat and political theorist Niccolò Machiavelli.
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 how to consider politics and ethics.
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.
