First Samnite War

The First Samnite War from 343 to 341 B.C. occurred when the cities of Campania called on Rome for assistance against the Samnite hill tribes. Marcus Valerius Corvus won a major victory at Mount Gaurus in 342 B.C., but could not conquer the Samnites. In the end, Rome did establish a virtual protectorate over Campania.
