I want to know the answer to the following question:
Where did Rome receive half of their army from?
All the background I'm provided with is that "Rome's military confederation with the other peoples of the Italian peninsula meant that half of Rome's army was provided by the Socii, such as the Etruscans, Umbrians, Apulians, Campanians, Samnites, Lucani, Bruttii, and the various southern Greek cities.". Is that enough to answer the question?
