When the system of incorporation was extended up to and perhaps even beyond its natural limits, the communities that were subsequently added had to submit to a position of subjection; for a pure hegemony as a permanent relation was intrinsically impossible.
Thus not through any arbitrary monopolizing of sovereignty, but through the inevitable force of circumstances, by the side of the class of ruling burgesses a second class of subjects took its place.
It was one of the primary expedients of Roman rule to subdivide the governed by breaking up the Italian confederacies and instituting as large a number as possible of comparatively small communities, and to graduate the pressure of that rule according to the different categories of subjects.

As Cato in the government of his household took care that the slaves should not be on too good terms with one another, and designedly fomented variances and factions among them, so the Roman community acted on a great scale.

The expedient was not generous, but it was effectual.
Aristocratic Remodelling of the Constitutions of the Italian Communities It was but a wider application of the same expedient, when in each dependent community the constitution was remodelled after the Roman pattern and a government of the wealthy and respectable families was installed, which was naturally more or less keenly opposed to the multitude and was induced by its material interests and by its wish for local power to lean on Roman support.

The most remarkable instance of this sort is furnished by the treatment of Capua, which appears to have been from the first treated with suspicious precaution as the only Italian city that could come into possible rivalry with Rome.

The Campanian nobility received a privileged jurisdiction, separate places of assembly, and in every respect a distinctive position; indeed they even obtained not inconsiderable pensions -- sixteen hundred of them at 450 -stateres- (about 30 pounds) annually--charged on the Campanian exchequer.
