From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
The position of these new communities of full burgesses was a compromise between that which had belonged to them hitherto as allied states, and that which by the earlier law would have belonged to them as integral parts of the Roman community. Their basis was in general the constitution of the former formally sovereign Latin community, or, so far as their constitution in its principles resembled the Roman, that of the Roman old-patrician-consular community; only care was taken to apply to the same institutions in the -municipium- names different from, and inferior to, those used in the capital, or, in other words, in the state.
A burgess-assembly was placed at the head, with the prerogative of issuing municipal statutes and nominating the municipal magistrates. A municipal council of a hundred members acted the part of the Roman senate. The administration of justice was conducted by four magistrates, two regular judges corresponding to the two consuls, and two market-judges corresponding to the curule aediles. The functions of the censorship, which recurred, as in Rome, every five years and, to all appearance, consisted chiefly in the superintendence of public buildings, were also undertaken by the supreme magistrates of the community, namely the ordinary -duumviri-, who in this case assumed the distinctive title of -duumviri- "with censorial or quinquennial power." The municipal funds were managed by two quaestors. Religious functions primarily devolved on the two colleges of men of priestly lore alone known to the earliest Latin constitution, the municipal pontifices and augurs.
