[Maraya1969]

Machiavellianism is "the employment of cunning and duplicity in statecraft or in general conduct".[1] The word comes from the Italian Renaissance diplomat and writer Niccolò Machiavelli, born in 1469, who wrote Il Principe (The Prince), among other works.
In modern psychology, Machiavellianism is one of the dark triad personalities, characterized by a duplicitous interpersonal style, a cynical disregard for morality and a focus on self-interest and personal gain.[2]


In the 16th century, immediately following the publication of The Prince, Machiavellianism was seen as a foreign plague infecting northern European politics, originating in Italy, and having first infected France. It was in this context that the St. Bartholomew's Day massacre of 1572 in Paris came to be seen as a product of Machiavellianism, a view greatly influenced by the Huguenot Innocent Gentillet, who published his Discours contre Machievel in 1576, which was printed in ten editions in three languages over the next four years.[3] Gentillet held, quite wrongly according to Sydney Anglo, that Machiavelli's "books [were] held most dear and precious by our Italian and Italionized [sic] courtiers" in France (in the words of his first English translation), and so (in Anglo's paraphrase) "at the root of France's present degradation, which has culminated not only in the St Bartholemew massacre but the glee of its perverted admirers".[4] In fact there is little trace of Machiavelli in French writings before the massacre, not that politicians telegraph their intentions in writing, until Gentillet's own book, but this concept was seized upon by many contemporaries, and played a crucial part in setting the long-lasting popular concept of Machiavellianism.[5]


The English playwrights William Shakespeare and Christopher Marlowe were enthusiastic proponents of this view. Shakespeare's Gloucester, later Richard III, refers to Machiavelli in Henry VI, Part III, for instance:
I can add colours to the chameleon,
Change shapes with Proteus for advantages,
And set the murderous Machiavel to school.
