War involved a need for armies of a different type. Spain was too far off for periodic reliefs, and the war demanded a more thorough training than was possible with these on and off soldiers. Accordingly men were enlisted for longer terms and paid. So the paid soldier first appeared in Roman affairs. And to pay was added booty. Cato distributed silver treasure among his command in Spain; and it is also on record that he attacked Scipio Africanus for distributing booty among his troops in Sicily. The introduction of military pay led on to a professional army, and this, a century later, to the disarmament of the ordinary Roman citizen, who was now drifting in an impoverished state into Rome and the larger towns. The great wars had been won, the foundations of the empire had been well and truly laid by the embattled farmers of Rome before 200 B.C. In the process the embattled farmers of Rome had already largely disappeared. The change that began after the Second Punic War was completed towards the close of the century in the reorganization of the army by Marius, as we will tell in its place. After his time we shall begin to write of "the army," and then of "the legions," and we shall find we are dealing with a new kind of army altogether, no longer held together in the solidarity of a common citizenship. As that tie fails, the legions discover another in esprit de corps, in their common difference from and their common interest against the general community. They begin to develop a warmer interest in their personal leaders, who secure them pay and plunder. Before the Punic Wars it was the tendency of ambitious men in Rome to court the plebeians; after that time they began to court the legions.
The history of the Roman Republic thus far, is in many respects much more modern in flavour, especially to the American or Western European reader, than anything that has preceded it. For the first time we have something like a self-governing "nation," something larger than a mere city state, seeking to control its own destinies. For the first time we have a wide countryside under one conception of law. We get in the Senate and the popular assembly a conflict of groups and personalities, an argumentative
