First Samnite War (343-341 BC)

The First, Second, and Third Samnite wars, between the early Roman Republic and the tribes of Samnium, extended over half a century, involving almost all the states of Italy, and ended in Roman domination of the Samnites. The tribes of Samnium, who held the Apennines to the southeast of Latium, were Rome's most formidable rivals.
