The Prince by Niccolo Machiavellil

Based largley on examples from the life of Cesare Borgia (son of Pope Alexander VI and sister of Lucrezia Borgia), this book was intended as practical advice for how to unify Italy with force. Machiavelli begins with the assumption that the end justifies the means -- so any action is permitted that leads to a unified Italy. His work has served for centuries as a handbook for would-be dictators and conquerors. According to Wikipedia: Niccolò di Bernardo dei Machiavelli (1469 – 1527) was an Italian diplomat, political philosopher, musician, poet and playwright. Machiavelli was a figure of the Italian Renaissance, and a servant of the Florentine republic. In June of 1498, following the ouster and execution of Savonarola, the Great Council elected Machiavelli as the Secretary to the second Chancery of the Republic of Florence. He is most famous — or notorious — for one of his shorter works, The Prince, sometimes described as a work of realist political theory. However, both that text and the more substantial republican Discourses on Livy — as well as History of Florence (commissioned by the Medici family) — were printed only after his death, all appearing in the early 1530s. In his own lifetime, while he circulated The Prince among friends, the only work Machiavelli promoted through printing was his dialogue on The Art of War. But generations from the sixteenth century onwards were most attracted and repelled by the cynical approach to power on display in The Prince, Discourses and History. Whatever Machiavellis own intentions (and they remain a matter of heated debate), his name became synonymous with ruthless politics, deceit and the pursuit of power by any means.
