The Prince Questions

A prince must lay strong foundations, Machiavelli argues in Chapter XII, “On Different Kinds of Troops, Especially Mercenaries.” Such foundations consist primarily of good laws and good arms. Because these are inextricably bound, Machiavelli explains that he will focus on arms rather than laws.

Armies are either composed of mercenaries, composed of auxiliaries, mixed, or the state’s own. The first two types are “useless and dangerous”: mercenaries, in particular, “will protect you from ruin only as long as nobody assaults you; in peace you are at their mercy, and in war at the mercy of your enemies.” The only incentive mercenaries have is money, and the weakness of Italy can be blamed on their kind. Machiavelli proceeds to list examples of secure republics with large armies of their own people (ancient Sparta, ancient Rome, contemporary Switzerland) and contrasts these with the Carthaginians, whose mercenary armies turned on their masters and almost overthrew them.
