The Greek cities of southern Italy called on King Pyrrhus of Epirus to
protect them from Roman encroachment. Though Pyrrhus was undefeated in
battle, his victories were so costly that he was forced to withdraw
from Italy in 275 BC, leaving Rome in control of Magna Graecia.
Rome battled a combined army of Samnites, Etruscans, Umbrians and Gauls
for control of Italy. At Sentinum, the two sides fought the largest
battle in Italian history up to that point.
After a five year break, hostilities resumed between the Romans and
Samnites. Despite early setbacks, Rome eventually emerged victorious in
304 BC. During these years a controversial politician, Appius Claudius,
initiated a series of ambitious public works projects that advanced
Roman civilization.
After a decade of peace, the Romans and Samnites returned to war. The
early years of fighting went well for Rome, but in 321 BC they were
handed a humiliating defeat at Caudine Forks.
The Romans fought a final war against their Latin neighbors from
340-338 BC. The Romans won a decisive victory and the Latin League was
abolished once and for all.
From 343-341 BC Rome fought a brief war against the Samnites, a
powerful hill tribe who would plague the Romans for the rest of the
century. The Romans won an inconclusive victory, but the war was only
the opening salvo in a long running struggle between the two peoples.
In the decades after the Gauls abandoned Rome to its fate, the Romans
were forced to battle both external threats and internal sedition. The
Plebes, saddled with debt from the reconstruction, forced through
reforms in 367 BC that finally gave them access to the most powerful
office of state: the Consulship.
