From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
The formally autonomous Latin and the other emancipated communities-thus including all those of Sicily and of Narbonese Gaul, so far as they were not burgess-communities, and a considerable number also in the other provinces--had not merely free administration, but probably unlimited jurisdiction; so that the governor was only entitled to interfere there by virtue of his-- certainly very arbitrary--administrative control.
No doubt even earlier there had been communities of full burgesses within the provinces of governors, such as Aquileia, and Narbo, and whole governors' provinces, such as Cisalpine Gaul, had consisted of communities with Italian constitution; but it was, if not in law, at least in a political point of view a singularly important innovation, that there was now a province which as well as Italy was peopled solely by Roman burgesses,(99) and that others promised to become such.
99. It is difficult to see why the bestowal of the Roman franchise on a province collectively, and the continuance of a provincial administration for it, should be usually conceived as contrasts excluding each other. Besides, Cisalpine Gaul notoriously obtained the -civitas- by the Roscian decree of the people of the 11th March 705, while it remained a province as long as Caesar lived and was only united with Italy after his death (Dio, xlviii. 12); the governors also can be pointed out down to 711. The very fact that the Caesarian municipal ordinance never designates the country as Italy, but as Cisalpine Gaul, ought to have led to the right view.
