Mare Nostrum

When the Second Punic War ended, the Mediterranean had changed masters. A balance that had endured for centuries between the Phoenician and the Italic worlds was broken, and the centre of gravity in Mediterranean history shifted westward. From that point on, the sea lay under Roman control.

For the generation that followed, this new order appeared natural, even inevitable. The Republic had fought for its survival and prevailed. But to those who still remembered the older world, the transformation was profound. A civilisation that had dominated the coasts of Africa, Spain, and the islands for centuries disappeared within a few decades. The sailors who had once treated every harbour as familiar ground faded into memory; their gods fell silent, their ports passed into Roman hands.

The Phoenicians had been among the earliest masters of the sea, the first to turn water into a route rather than a barrier. From their red sands and purple coasts they ventured westward, founding settlements wherever trade and wind allowed. Their ships connected the eastern Mediterranean with the Atlantic beyond the Pillars of Hercules. Cities such as Tyre, Sidon, Byblos, Gades, and Carthage formed a chain of exchange that encircled the known world. Their strength lay less in conquest than in connection. They traded in metals, dyes, grain, and timber, and carried with them techniques, beliefs, and customs. They transmitted alphabets to Greece, crafts to Sicily, and luxuries to every land willing to pay.

Rome, by contrast, came late to the sea. For generations her wars were fought on Italian soil, where power was measured in legions, walls, and fields rather than ships. Roads mattered more than harbours. Roman habits were agrarian and military, and the sea was long regarded as the realm of merchants, pirates, and foreigners. Only in the third century BCE did necessity overcome indifference.

The First Punic War forced Rome to master an unfamiliar domain. Facing the most experienced naval power of the age, the Romans built fleets by copying Carthaginian vessels and trained their crews on wooden benches set up on land. Discipline compensated for inexperience. Within a single generation Rome had secured Sicily, Sardinia, and Corsica, gaining control of the western Mediterranean’s strategic gateways.

Victory, however, did not bring reassurance. It produced a new logic of security. To be safe, Rome concluded, she must command the sea; to command it fully, rivals had to be eliminated. The continued existence of Carthage appeared intolerable. The Phoenicians had honoured their treaties, but that fact carried little weight. They still possessed ships, wealth, and influence. In Roman eyes, that alone made them dangerous.

This attitude, which later generations might judge severe, appeared to the Romans entirely rational. Power shared was power endangered. Once supremacy was achieved, Rome had little tolerance for lasting equals.

When Carthage finally fell, it was not merely a city that vanished, but a particular way of engaging with the Mediterranean. The Phoenicians had believed commerce could bind distant communities together, even if coercion accompanied it. The Romans placed their faith in law enforced by force. The sea that had once carried overlapping networks of trade and culture became an imperial basin governed from a single centre.

Yet history’s ironies soon asserted themselves. Rome absorbed much of what she had destroyed. Roman merchants replaced Punic traders, Roman fleets sailed Punic routes, and Roman governors presided in former Phoenician ports. The instruments of maritime power changed hands, while the habits of domination endured.

By the time Sulla was born, this transformation was complete. The Mediterranean—now commonly called mare nostrum, “our sea”—had become the artery of Roman life. Grain from Africa sustained the capital; silver from Spain paid the armies; slaves from the East filled Italian estates. The Republic had become dependent on the world it ruled.

That success carried its own dangers. The empire that began as a defensive necessity hardened into a habit of expansion. Wealth eroded older restraints. Provinces were treated as sources of revenue, not communities to be governed. Governors exercised authority with little oversight, and the Senate increasingly resembled a consortium of interested families dividing the proceeds of conquest. The qualities that had defeated Carthage—discipline, endurance, civic obligation—gave way to competition for profit and status.

Mommsen observed that after Carthage’s destruction Rome no longer possessed a foreign policy in the traditional sense, but an appetite. Each new war was justified as a measure of security, each annexation as prevention. Expansion became routine, driven by the same fear that had once compelled Rome to remove her greatest rival.

Fear, however, does not remain outward-facing. As the Republic expanded, Romans began to mistrust one another much as they had once mistrusted the Phoenicians. The sense of shared purpose weakened. The rewards of empire accumulated among the senatorial and equestrian orders, while the small farmers and artisans who had once formed Rome’s backbone declined.

In the countryside, peasant holdings disappeared, replaced by large estates worked by slaves captured abroad. In the cities, dispossessed citizens depended increasingly on grain distributions and public entertainments. The Republic that had once prided itself on restraint learned to rely on spectacle and subsidy.

This was the inheritance left by victory. The generation that conquered the Mediterranean handed its successors an empire difficult to sustain and a liberty whose foundations had been eroded.

Roman judgments of the Phoenicians as clever but unreliable merchants were at once accurate and misleading. Carthaginian politics could be pragmatic and self-interested, yet Rome adopted similar practices once supremacy was secure. After the Punic Wars, Rome increasingly treated the world not as a community of allies but as a marketplace. Office, loyalty, and even war itself acquired measurable value. The traits once criticised in the Phoenicians—calculation, flexibility, and opportunism—became central to Roman policy.

Seen in retrospect, the Punic Wars mark a turning point not only in power but in character. Before them, Rome remained a republic of citizens bound by shared obligation. After them, she stood on the threshold of empire. The decades between Hannibal’s defeat and Sulla’s birth were years of uneasy prosperity, peace accompanied by slow decay. Republican forms endured, but the spirit animating them had altered.

Sulla’s generation matured in the shadow of that change. The virtues of the past survived largely as stories repeated by elders; the lived reality was inequality, rivalry, and the pursuit of advancement. They inherited the triumphs of Scipio Africanus without his restraint, and learned early that success was expected while moderation was suspect.

The sea that had once united Rome and Carthage in rivalry now reflected Rome’s own contradictions. Fleets brought wealth and labour to Italy, but also temptation—the allure of luxury and the illusion of unlimited command. Mare nostrum was at once achievement and burden.

From Spain to Syria, governors enriched themselves faster than the state could restrain them. Equestrian companies farming the taxes of Asia drained the provinces to satisfy investors at Rome. The Senate, divided between defenders of privilege and reformers courting the crowd, no longer spoke for the Republic as a whole, but for competing interests.

In this climate, Carthage acquired new symbolic meaning. To conservatives, it warned of how wealth could corrode discipline. To the ambitious, it demonstrated how audacity could reshape the world. Hannibal’s name, once invoked in fear, became a measure of genius. The rising commanders of Sulla’s youth—Marius, Pompey, and later Caesar—absorbed these lessons.

The destruction of Carthage secured Rome against external rivals, but it also removed the final check on internal decay. A city that no longer feared enemies abroad began to generate them at home. Political struggle increasingly resembled warfare by other means, waged not for survival but for dominance.

The chain that began with Rome’s fear of Carthage ended in the Republic’s fear of itself. It is one of history’s sharper ironies that Sulla, who would later claim to restore order, was born into a world shaped by victory—a world in which order had already been undermined.

The Mediterranean lay obedient under Roman power. Phoenician ports became Roman provinces, trade routes were patrolled by Roman fleets, and the gods of Carthage faded from memory. Yet beneath that silence lingered echoes of the vanished world: the rhythm of oars, the calls of merchants, the languages of Tyre and Sidon carried by the wind. Rome had achieved what seemed necessary, but necessity rarely guides wisdom.

What was destroyed was not only a rival state, but a balance in which commerce and power could coexist without complete subjugation. From that moment onward, the Republic recognised only one form of greatness—the greatness born of war.

When Sulla entered the world, he inherited both that greatness and its burden. The Mediterranean was his cradle, but also his legacy of restlessness. The sea once claimed by the Phoenicians now belonged to Rome, yet neither had ever truly possessed it. It belonged instead to the will to dominate—that restless impulse which, once awakened, no state ever fully lays to rest.
