サムニウム戦争
The period following the end of the Latin War (340–338 BC) and of the Samnite Wars (343–290) saw the transformation of the Roman Republic from a powerful but beleaguered city-state into the hegemonic power of the Italian peninsula. This was accompanied by profound changes in its constitution and army. Internally, the critical development was the emergence of the senate as the all-powerful organ of state.
