Niccolo Machiavelli 

That Machiavelli’s name has become synonymous with cold-eyed political calculation only heightens the intrinsic fascination of The Prince–the world’s preeminent how-to manual on the art of getting and keeping power, and one of the literary landmarks of the Italian Renaissance. Written in a vigorous, straightforward style that reflects its author’s realism, this treatise on states, statecraft, and the ideal ruler is essential reading for anyone seeking to understand how human society actually works.
