A well-educated son of Florence, Machiavelli was originally in charge of the Florentine Republic's militia, but in 1512 the city fell to papal forces led by Cardinal Giovanni de Medici, who thus restored the Medici family to power. Machiavelli was accused of conspiracy, imprisoned, tortured, and eventually exiled from his beloved Florence, and it was during this period that he produced his most famous works. While attempting to ingratiate himself to the Medicis, the historically minded Machiavelli looked to the imperial ambitions and past glories of the Roman Republic as a contrast to the perceived failures of his contemporaries.
For Machiavelli, the hunger for power and glory was inextricable from human nature, and any serious attempt to rule must take this into account. In his revolutionary The Prince and Discourses--both excerpted here--Machiavelli created the first truly modern analysis of power.
