So long as the Latin confederacy continued open, the bounds of Latium had advanced with the establishment of new federal cities: but as the later Latin colonies had no share in the Alban festival, they were not regarded geographically as part of Latium.

For this reason doubtless Ardea and Circeii were reckoned as belonging to Latium, but not Sutrium or Tarracina.
Isolation of the Later Latin Cities as Respected Private Rights But not only were the places on which Latin privileges were bestowed after 370 kept aloof from the federal association; they were isolated also from one another as respected private rights.

While each of them was allowed to have reciprocity of commercial dealings and probably also of marriage (-commercium et conubium-) with Rome, no such reciprocity was permitted with the other Latin communities.
The burgess of Satrium, for example, might possess in full property a piece of ground in Rome, but not in Praeneste; and might have legitimate children with a Roman, but not with a Tiburtine, wife.( 18) Prevention of Special Leagues If hitherto considerable freedom of movement had been allowed within the confederacy, and for example the six old Latin communities, Aricia, Tusculum, Tibur, Lanuvium, Cora, and Laurentum, and the two new Latin, Ardea and Suessa Pometia, had been permitted to found in common a shrine for the Aricine Diana; it is doubtless not the mere result of accident that we find no further instance in later times of similar separate confederations fraught with danger to the hegemony of Rome.
Revision of the Municipal Constitutions.

Police Judges We may likewise assign to this epoch the further remodelling which the Latin municipal constitutions underwent, and their complete assimilation to the constitution of Rome.

If in after times two aediles, intrusted with the police-supervision of markets and highways and the administration of justice in connection therewith, make their appearance side by side with the two praetors as necessary elements of the Latin magistracy, the institution of these urban police functionaries, which evidently took place at the same time and at the instigation of the leading power in all the federal communities, certainly cannot have preceded the establishment of the curule aedileship in Rome, which occurred in 387; probably it took place about that very time.
