In other respects these colonial foundations were based, doubtless, like the older ones, on a decree of the people, but only indirectly, in so far as the regent constituted them by virtue of the clause of the Valerian law to that effect; in reality they originated from the ruler's plenitude of power, and so far recalled the freedom with which the former regal authority disposed of the state-property.
But, in so far as the contrast between the soldier and the burgess, which was in other instances done away by the very sending out of the soldiers or colonists, was intended to remain, and did remain, in force in the Sullan colonies even after their establishment, and these colonists formed, as it were, the standing array of the senate, they are not incorrectly designated, in contradistinction to the older ones, as military colonies.
The Cornelian Freedmen in Rome Akin to this practical constituting of a standing army for the senate was the measure by which the regent selected from the slaves of the proscribed upwards of 10,000 of the youngest and most vigorous men, and manumitted them in a body.

These new Cornelians, whose civil existence was linked to the legal validity of the institutions of their patron, were designed to be a sort of bodyguard for the oligarchy and to help it to command the city populace, on which, indeed, in the absence of a garrison everything in the capital now primarily depended.
Abolition of the Gracchan Institutions These extraordinary supports on which the regent made the oligarchy primarily to rest, weak and ephemeral as they doubtless might appear even to their author, were yet its only possible buttresses, unless expedients were to be resorted to--such as the formal institution of a standing army in Rome and other similar measures--which would have put an end to the oligarchy far sooner than the attacks of demagogues.

The permanent foundation of the ordinary governing power of the oligarchy of course could not but be the senate, with a power so increased and so concentrated that it presented a superiority to its non-organized opponents at every single point of attack.

The system of compromises followed for forty years was at an end.

The Gracchan constitution, still spared in the first Sullan reform of 666, was now utterly set aside.
