The Peucetians were an Iapygian tribe which inhabited western and central Apulia in classical antiquity.

Two other Iapygian tribes, the Daunians and the Messapians, inhabited northern and southern Apulia respectively. All three tribes spoke the Messapian language, but had developed separate archaeological cultures by the seventh century BC; however, in Peucetian territory ancient Greek and Oscan language were spoken as well, as the legends of the currencies from Rubi and Azetium were trilingual. Peucetians lived in the eponymous region Peucetia, which was bordered by the Ofanto river and the Murge in the north, the Bradano river in the west and the territories of the Greek colony of Taras and the Messapians in the south. This region is mostly coincident with the Metropolitan City of Bari and parts of the provinces of Taranto and Barletta-Andria-Trani today.

The Hirpini (Latin: Hirpini) 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, while the plains on each side, and the lower ranges that bounded them, belonged to their more fortunate neighbors. The mountain basin formed by the three tributaries of the Vulturnus (modern Volturno)—the Tamarus (modern Tammaro), Calor (modern Calore), and Sabatus (modern Sabato), which, with their valleys, unite near Beneventum, surrounded on all sides by lofty and rugged ranges of mountains—is the center and heart of their territory. They occupied the Daunian Mountains to the north, while its more southern portion comprised the upper valley of the Aufidus (modern Ofanto) and the lofty group of mountains where that river takes its rise.

Canosa di Puglia, generally known simply as Canosa (Canosino: Canaus), is a town and comune in the province of Barletta-Andria-Trani, Apulia, southern Italy. It is located between Bari and Foggia, on the northwestern edge of the plateau of the Murgia which dominates the Ofanto valley and the extensive plains of Tavoliere delle Puglie, ranging from Mount Vulture at the Gargano, to the Adriatic coast. Canosa, the Roman Canusium, is considered the principal archaeological center of Apulia, and is one of the oldest continually inhabited cities in Italy. A number of vases and other archaeological finds are located in local museums and private collections. It is not far from the position on the Ofanto River where the Romans found refuge after the defeat of the Battle of Cannae and is the burial place of Bohemund I of Antioch.

Daunian Mountains (in Italian Monti della Daunia or Monti Dauni, or also improperly Subappennino Dauno) are a mountain range in southern Italy, constituting the eastern appendix of the Campanian Apennines. They occupy the western fringe of Capitanata and the border of Apulia with Molise and Campania; the range takes its name from an ancient tribe, the Dauni, although it was strongly held by Hirpini instead.

The mountains and hills are bounded northwards by the Fortore valley, eastwards by the Tavoliere delle Puglie, southwards by the upper Ofanto valley. The chain is formed by sandstone terrains, and is the source of a series of small streams which flow through the Tavoliere into the Adriatic Sea. The highest peak is Monte Cornacchia, at 1,151 metres (3,776 ft).

The Tavoliere delle Puglie (Italian: [tavoˈljɛːre delle ˈpuʎʎe]; lit. 'Table of the Apulias') is a plain in northern Apulia, southern Italy, occupying nearly a half of the Capitanata traditional region. It covers a surface of c. 3,000 km, once constituting a sea bottom: it is bounded by the Daunian Pre-Apennines on the West, the Gargano Promontory and the Adriatic Sea on the East, by the Fortore river on the north, and the Ofanto river on the south. It is the largest Italian plain after the Po Valley.

The name Tavoliere derives from the Medieval Latin term Tabularium, a table on which Transumanza officials classified the areas devoted to sheep farming.
