Roman Empire's Mediterranean Unity Was Partial, Unequal, and Enforced by Violence, Historians Argue

According to TheCollector, the Roman Empire managed to bring together most Mediterranean cultures under one political framework for many centuries, though the degree of cultural and social integration varied. Roman authority spanned from Northern Britain and Gaul to Hispania, North Africa, Greece, the Levant, and Egypt, collectively known as Mare Nostrum. This expansion required centuries of military campaigns, including the Punic Wars, followed by the establishment of governance. The Pax Romana (27 BC - AD 180) provided stability to a region housing a quarter of the ancient world's populace. A standardized administration, imperial taxes, and military outposts helped unify provinces, while citizenship fostered connections to Rome. Although a free trade zone developed, prosperity was largely concentrated among the elites. After the split of the Eastern and Western empires, local leaders began to take control in Roman Britain post-AD 410.
