The Lucanians () were an Italic tribe living in Lucania, in what is now southern Italy, who spoke the Oscan language, a member of the Italic languages. Today, the inhabitants of the Basilicata region are still called Lucani, and so is their dialect.

Thurii (; ; ), called also by some Latin writers Thūrium (compare , in Ptolemy), and later in Roman times also Cōpia and Cōpiae, was an ancient Greek city situated on the Gulf of Taranto, near or on the site of the great renowned city of Sybaris, whose place it may be considered as having taken. The ruins of the city can be found in the Sybaris archaeological park near Sibari in the Province of Cosenza, Calabria, Italy.

The Iapygians or Apulians () were an Indo-European-speaking people who inhabited Iapygia in southeastern Italy (modern Apulia), from the early first millennium BC until the first century BC. They were traditionally divided into three tribal groups: the Daunians, Peucetians and Messapians.

The Marsi were an Italic people of ancient Italy, whose chief centre was Marruvium, on the eastern shore of Lake Fucinus (which was drained in the time of Claudius). The area in which they lived is now called Marsica. They originally spoke a language now termed Marsian which is attested by several inscriptions.

The Hernici were an Italic tribe of ancient Italy, whose territory was in Latium between the Fucine Lake and the Sacco River (Trerus), bounded by the Volsci on the south, and by the Aequi and the Marsi on the north.

The socii ( ) or foederati ( ) were confederates of Rome and formed one of the three legal denominations in Roman Italy (Italia) along with the core Roman citizens (Cives Romani) and the extended Latini. The Latini, who were simultaneously special confederates (Socii Latini) and semi-citizens (Cives Latini), derived their name from the Italic people of which Rome was part (the Latins) but did not coincide with the region of Latium in central Italy as they were located in colonies throughout the peninsu

The Marrucini were an Italic tribe that occupied a small strip of territory around the ancient Teate (modern Chieti), on the east coast of Abruzzo, Italy, limited by the Aterno and Foro Rivers. Other Marrucinian centers included Ceio (San Valentino in Abruzzo Citeriore), Iterpromium (whose ruins are under the Abbey of San Clemente at Casauria), Civitas Danzica (Rapino), and the port of Aternum (Pescara), shared with the Vestini.

The Hirpini (Latin: '') were an ancient Samnite tribe of Southern Italy. While generally regarded as having been Samnites, sometimes they are treated as a distinct and independent nation. They inhabited the southern portion of Samnium, in the more extensive sense of that name, roughly the area now known as Irpinia from their name—a mountainous region bordering on Basilicata towards the south, on Apulia to the east, and on Campania towards the west. No marked natural boundary separated them from these neighboring nations, but they occupied the lofty masses and groups of the central Apennines, w

The Caudini were a Samnite tribe that lived among the mountains ringing Campania and in the valleys of the Isclero and Volturnus rivers. Their capital was at Caudium, but it seems certain that the appellation was not confined to the citizens of Caudium and its immediate territory.

The Frentani were an Italic tribe occupying the tract on the southeast coast of the Italian peninsula from the Apennines to the Adriatic, and from the frontiers of Apulia to those of the Marrucini. They were bounded on the west by the Samnites, with whom they were closely connected, and from whom they were originally descended. Hence Scylax assigns the whole of this line of coast, from the frontiers of Apulia to those of Picenum, to the Samnites. Their exact limits are less clearly defined,
