The First, Second, and Third Samnite Wars (343–341 BC, 326–304 BC and 298–290 BC) were fought between the Roman Republic and the Samnites, who lived on a stretch of the Apennine Mountains to the south of Rome and the north of the Lucanians. The first of these wars was the result of Rome's intervening to rescue the Campanian city of Capua from a Samnite attack. The second one was the result of Rome's intervention in the politics of the city of Naples and developed into a contest over the control of much of central and southern Italy. The third war also involved a struggle over the control of this part of Italy. The wars extended over half a century and the peoples to the east, north and west of Samnium (land of the Samnites) as well as the peoples of central Italy north of Rome (the Etruscans, Umbrians and Picenti) and the Senone Gauls got involved to various degrees and at various points in time. The Samnites were one of early Rome's most formidable rivals.

By the time of the first of these wars, the southward expansion of Rome’s territory had reached the River Liris (see Liri), which was the boundary between Latium (Land of the Latins) and Campania. This river is now called Garigliano and it is the boundary between the modern regions of Lazio and Campania. In those days the name Campania referred to the plain between the coast and the Apennine Mountains which stretched from the River Liris down to the bays of Naples and Salerno. The northern part of this area was inhabited by the Sidicini, the Aurunci and the Ausoni (a subgroup of the Aurunci). The central and southern part was inhabited by the Campanians, who were people who had migrated from Samnium (Land of the Samnites) and were closely related to the Samnites, but had developed their distinctive identity. The Samnites were a confederation of four tribes who lived on the mountains to the east of Campania and were the most powerful people in the area. The Samnites, Campanians and Sidicini spoke Oscan languages. Their languages were part of the Osco-Umbrian linguistic family which also included Umbrian and the Sabellian languages to the north of Samnium. The Lucanians who lived to the south were also Oscan speakers.

Diodorus Siculus and Livy report that in 354 BC Rome and the Samnites concluded a treaty, but neither lists the terms agreed upon. Modern historians have proposed that the treaty established the river Liris as the boundary between their spheres of influence, with Rome's lying to its north and the Samnites' to its south. This arrangement broke down when the Romans intervened south of the Liris to rescue the Campanian city of Capua (just north of Naples) from an attack by the Samnites.
