Niccolò Machiavelli 
The Prince 

The Prince (Italian: Il Principe [il ˈprintʃipe]) is a 16th-century political treatise by the Italian diplomat and political theorist Niccolò Machiavelli. From his 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. This was carried out with the permission of the Medici pope Clement VII, but "long before then, in fact since the first appearance of The Prince in manuscript, controversy had swirled about his writings".
