What helped the Romans to conquer all of Italy?

First, of course, is the fighting resilience of the Romans. Hardened in numerous battles, they were not afraid of defeat. On the contrary, defeats forced them to get up again and go into battle. In addition, the Romans were cunning. They understood that not everyone can be defeated in a fair fight, therefore they began to play off some states among themselves. They did so that they themselves were exhausted in bloody battles. Divide and rule – that was the principle of the warriors of Rome.
