To look therefore merely to the direct innovations, possibly to the mere change in the duration of the supreme magistracy, is altogether to mistake the broad import of the first Roman revolution: its indirect effects were by far the most important, and vaster doubtless than even its authors anticipated.
The New Community This, in short, was the time when the Roman burgess-body in the later sense of the term originated.

The plebeians had hitherto been -- metoeci-- who were subjected to their share of taxes and burdens, but who were nevertheless in the eye of the law really nothing but tolerated aliens, between whose position and that of foreigners proper it may have seemed hardly necessary to draw a definite line of distinction.

They were now enrolled in the lists as burgesses liable to military service, and, although they were still far from being on a footing of legal equality--although the old burgesses still remained exclusively entitled to perform the acts of authority constitutionally pertaining to the council of elders, and exclusively eligible to the civil magistracies and priesthoods, nay even by preference entitled to participate in the usufructs of burgesses, such as the joint use of the public pasture--yet the first and most difficult step towards complete equalization was gained from the time when the plebeians no longer served merely in the common levy, but also voted in the common assembly and in the common council when its opinion was asked, and the head and back of the poorest -- metoikos-- were as well protected by the right of appeal as those of the noblest of the old burgesses.
One consequence of this amalgamation of the patricians and plebeians in a new corporation of Roman burgesses was the conversion of the old burgesses into a clan-nobility, which was incapable of receiving additions or even of filling up its own ranks, since the nobles no longer possessed the right of passing decrees in common assembly and the adoption of new families into the nobility by decree of the community appeared still less admissible.

Under the kings the ranks of the Roman nobility had not been thus closed, and the admission of new clans was no very rare occurrence: now this genuine characteristic of patricianism made its appearance as the sure herald of the speedy loss of its political privileges and of its exclusive estimation in the community.

The exclusion of the plebeians from all public magistracies and public priesthoods--while they were admissible to the position of officers and senators--and the maintenance, with perverse obstinacy, of the legal impossibility of marriage between old burgesses and plebeians, further impressed on the patriciate from the outset the stamp of an exclusive and wrongly privileged aristocracy.
A second consequence of the new union of the burgesses must have been a more definite regulation of the right of settlement, with reference both to the Latin confederates and to other states.
