10.3 Expansion and Conquest of the Italian Peninsula

Rome's conquest of Italy spanned centuries, transforming the peninsula. Starting with early victories over Latin cities, Rome gradually extended its reach through wars with Samnites, Greeks, and Gauls. Key battles like Sentinum and Asculum solidified Roman dominance.

Rome's success stemmed from military innovations, diplomatic strategies, and infrastructure development. The conquest reshaped Italy's political, social, and economic landscape. It centralized power in Rome, spread Latin culture, and created a shared Italian identity under Roman rule.
