Though Interamna Lirenas was in the area now known as “Italy,” it had been set up by Rome as a “Latin” colony in 312 B.C.E., Launaro explains: “As such, its inhabitants were not considered Roman citizens, but citizens of a formally independent community, bound to Rome by a treaty of close political and military alliance. Following the so-called Social War (‘war with the allies’, from 91 to 88 B.C.E., Interamna was granted the status of a Roman municipium and its inhabitants became Roman citizens.”
While still having a large degree of administrative autonomy, its inhabitants would have then been entitled to vote in Rome’s assemblies and even run for public office, he explains.
