The method which consists in forming leagues, of which I have spoken above as having been adopted by the Etruscans, the Achaians, and the Etolians of old, and in our own days by the Swiss, is the next best after that followed by the Romans, for as in this way there can be no great extension of power, two advantages result: first, that you do not readily involve yourself in war; and, second, that you can easily preserve any little acquisition which you may make. The reason why you cannot greatly extend your power is, that as your league is made up of separate States with distinct seats of government, it is difficult for these to consult and resolve in concert. The same causes make these States careless to enlarge their territories; because acquisitions which have to be shared among many communities are less thought of than those made by a single republic which looks to enjoy them all to itself. Again, since leagues govern through general councils, they must needs be slower in resolving than a nation dwelling within one frontier. Moreover, we find from experience that this method has certain fixed limits beyond which there is no instance of its ever having passed; by which I mean that some twelve or fourteen communities may league themselves together, but will never seek to pass beyond that limit: for after associating themselves in such numbers as seem to them to secure their safety against all besides, they desire no further extension of their power, partly because no necessity compels them to extend, and partly because, for the reasons already given, they would find no profit in extending. For were they to seek extension they would have to follow one of two courses: either continuing to admit new members to their league, whose number must lead to confusion; or else making subjects, a course which they will avoid since they will see difficulty in making them, and no great good in having them. Wherefore, when their number has so increased that their safety seems secured, they have recourse to two expedients: either receiving other States under their protection and engaging for their defence (in which way they obtain money from various quarters which they can easily distribute among themselves); or else hiring themselves out as soldiers to foreign States, and drawing pay from this or the other prince who employs them to carry out his enterprises; as we see done by the Swiss at the present day, and as we read was done in ancient times by certain of those nations whom we have named above. To which we have a witness in Titus Livius, who relates that when Philip of Macedon came to treat with Titus Quintius Flamininus, and while terms were being discussed in the presence of a certain Etolian captain, this man coming to words with Philip, the latter taunted him with greed and bad faith; telling him that the Etolians were not ashamed to draw pay from one side, and then send their men to serve on the other; so that often the banner of
