For more than a century subsequent to his death in 1527, Niccolò Machiavelli was known to the larger world as a counselor of princes, as an enemy to morality and the Christian religion, and as an inspiration to the advocates of raison d'état. It was not until after the execution of Charles I in January 1649 that he would become almost equally famous also as an advocate for republican rule.

There is no great mystery in this. Machiavelli's Prince is, at least on the surface, a much more accessible book than his Discourses on Livy. It is shorter, pithier, and more vigorous, and it enjoyed a grand succès de scandale from the very first. In contrast, the Discourses on Livy is long, subtle, complex, and difficult to decipher. In short, the work in which republicanism looms large is as unattractive to the casual reader as The Prince is alluring. Even now, the longer book is much more rarely read.

Of course, from the outset, there were those who argued that Machiavelli revealed his true opinions only in his Discourses on Livy. Within six years of the appearance of the Florentine's two great masterpieces in printed form, an inquisitive and well-connected English visitor to Florence named Reginald Pole was told by one or more of Machiavelli's compatriots that the author of the Discourses on Livy had written The Prince solely in order to trip up the Medici and bring about their demise. Machiavelli had purportedly acknowledged as much himself.
