The Punic Wars: Rome vs. Carthage for the Mediterranean

For more than a century, from 264 to 146 BCE, the two greatest powers of the western Mediterranean fought a series of wars that would determine the fate of the ancient world. On one side was Rome, a rising Italian state whose legions had already conquered the Italian peninsula. On the other was Carthage, a wealthy Phoenician colony on the coast of modern Tunisia, mistress of the western Mediterranean, mistress of the sea, mistress of Spain, and the mother of mercenary armies that included some of the most brilliant commanders of the ancient world. By the end of the conflict Carthage had been utterly destroyed, its population killed or enslaved, its fields salted, and its territory annexed as the Roman province of Africa. Rome was the unrivalled master of the Mediterranean.

These were the Punic Wars — “Punic” from the Latin Poeni, the word for Carthaginians, derived from the Greek Phoinikes for Phoenicians. The Romans would remember them as the wars that had nearly destroyed them and that, in the end, had made them great. The most famous general of the wars, Hannibal Barca, would remain, for two thousand years, the archetype of the brilliant enemy.

Carthage: The Other Superpower

Carthage had been founded, according to tradition, by Phoenician colonists from Tyre in the 9th century BCE. By the 3rd century BCE it was the largest and richest city of the western Mediterranean, with a population of perhaps 400,000, a sophisticated mercantile economy, a navy that dominated the western seas, and a network of trading posts and colonies stretching from the Atlantic coast of Spain to the Aegean. Carthaginian ships carried tin from Cornwall, silver from Spain, gold from West Africa, and grain from Sardinia and Sicily.

Carthaginian society was dominated by an oligarchy of wealthy merchant families. The two chief magistrates, called suffetes, were elected annually from among the leading families, and a council of elders and a popular assembly shared in government. The city’s famous army was not a citizen militia but a professional force of mercenaries — Libyans, Numidians, Spaniards, Gauls, and others — hired with the silver that flowed into Carthage’s coffers from its trade. The mercenaries were brilliant soldiers, especially the Numidian cavalry, but they were also expensive and unreliable. The revolt of the mercenary army after the First Punic War nearly destroyed Carthage.

The First Punic War (264–241 BCE)

The First Punic War began as a local dispute over Sicily. Rome intervened in a conflict between the cities of Messana and Syracuse, both on the east coast of Sicily, and was soon drawn into a war against Carthage, which held the western half of the island. What had been a small-scale intervention became, almost accidentally, a major war for control of the Mediterranean.

Neither side was prepared. Rome had no navy; Carthage had no army of citizen-soldiers willing to campaign far from home. The Romans, characteristically, built a fleet from scratch — modeled, by tradition, on a captured Carthaginian quinquereme — and within a few years the two powers were contesting the sea as well as the land.

The war lasted 23 years and was fought on a scale and with a ferocity that shocked both sides. Major naval battles were fought at Mylae (260 BCE) and the Aegates Islands (241 BCE). On land, the Romans besieged and captured the Carthaginian strongholds in Sicily. The turning point came in 241 BCE, when the Roman fleet, under the consul Gaius Lutatius Catulus, won a decisive naval victory off the Aegates Islands. Carthage sued for peace.

The terms were harsh. Carthage had to evacuate Sicily, surrender the islands of Sardinia and Corsica, pay a huge indemnity of 3,200 talents of silver over ten years, and accept that Rome now controlled the sea lanes of the central Mediterranean. Sicily became the first Roman overseas province.

Between the Wars: The Barcid Dynasty in Spain

The loss of Sicily and Sardinia was a humiliation that the Carthaginian general Hamilcar Barca was determined to revenge. Hamilcar spent the years after the war rebuilding Carthaginian power in Spain, where he and his successors carved out a new empire in the southern and eastern parts of the peninsula, exploiting the rich silver mines to raise new armies and new fleets. Hamilcar died in 228 BCE, fighting the Iberian tribes, and was succeeded by his son-in-law Hasdrubal, who extended Carthaginian control as far north as the river Ebro.

When Hasdrubal was assassinated in 221 BCE, command passed to Hamilcar’s son, Hannibal, then only 26 years old. Hannibal was one of the great military commanders of antiquity. He had grown up in his father’s camp, had been sworn at the age of nine to eternal hatred of Rome, and had spent his adult life mastering the art of war. He would prove to be the most dangerous enemy Rome ever faced.

The Second Punic War (218–201 BCE)

In 219 BCE, Hannibal attacked the Roman-allied city of Saguntum in Spain, in violation of the treaty that had ended the First Punic War. Rome demanded his surrender. Hannibal refused, and the Second Punic War began.

What followed astonished the ancient world. Hannibal marched his army — perhaps 90,000 men and 37 elephants — from Spain, through southern Gaul, and over the Alps into Italy. The crossing of the Alps, in the autumn of 218 BCE, was a feat of endurance that has been debated by military historians for two thousand years. The exact route is unknown, but the achievement is not: Hannibal brought an army, with its elephants and cavalry, across the highest mountains in Europe and into the heart of Italy.

The Romans, who had expected the war to be fought in Spain, were caught off guard. Hannibal won three stunning victories in his first eighteen months in Italy.

At the Battle of the Trebia in December 218 BCE, Hannibal lured the Roman consul Sempronius Longus into a trap and destroyed his army in the freezing waters of the Trebia river. At the Battle of Lake Trasimene in June 217 BCE, Hannibal ambushed the army of the consul Gaius Flaminius in a defile by the lake and slaughtered it, killing Flaminius himself. And at the Battle of Cannae in August 216 BCE, Hannibal achieved the masterpiece of his career, the perfect double envelopment: a weakened center that gave way, drawing the Romans into a pocket, and cavalry attacks on both flanks that closed the trap and destroyed eight Roman legions — perhaps 50,000 to 70,000 men — in a single afternoon.

Cannae was the worst defeat in Roman history. It remains, to this day, a textbook example of how a smaller force can defeat a much larger one, and it was studied with obsessive care by later commanders, including the American Civil War generals. For more on these and other decisive engagements, see famous Roman battles.

After Cannae, much of southern Italy defected to Hannibal. The Greek cities of the south, the Samnites, the Lucanians, and even parts of the Carthaginian-held Sicily joined his coalition. Rome itself was threatened. Yet the Romans did not panic. The Senate refused to ransom the captured soldiers. The dictator Quintus Fabius Maximus, nicknamed “Cunctator” — the Delayer — pursued a strategy of avoiding pitched battles, harrying Hannibal’s supply lines, and waiting for him to make a mistake. It was a strategy that required extraordinary patience, and it ultimately worked.

The war dragged on for another thirteen years. Hannibal marched up and down Italy, winning battles but never able to take Rome itself. His army shrank, his Italian allies failed to deliver decisive support, and his brother Hasdrubal, marching from Spain to join him, was defeated and killed at the Battle of the Metaurus in 207 BCE. The turning point came in 204 BCE, when the Roman Senate voted to take the war to Africa itself, and a young commander named Publius Cornelius Scipio, later known as Scipio Africanus, invaded North Africa with an army.

Scipio Africanus and the Battle of Zama

Scipio was one of the great military geniuses of Roman history. He had fought in Spain as a young man, had taken command of the Roman forces there at the age of 27, and within four years had driven the Carthaginians out of the Iberian peninsula. The invasion of Africa was his masterstroke.

Carthage, threatened in its homeland, recalled Hannibal from Italy. The two armies met at Zama in 202 BCE, in what is now Tunisia. Hannibal’s army was smaller, his cavalry was inferior, and his famous elephants, terrified by Roman trumpets and javelins, turned back on his own troops. Scipio’s legions enveloped the Carthaginian infantry and Hannibal’s army was decisively defeated. Hannibal himself escaped, but the war was over.

The peace terms were severe. Carthage had to surrender its fleet, pay an indemnity of 10,000 talents over fifty years, give up all its territory outside Africa, and agree to wage war only with Roman consent. Carthage remained independent, but as a client state of Rome. For a detailed account of Scipio’s campaigns, see the entry on the Battle of Zama and the broader story of Roman military tactics.

Hannibal, after the war, became chief magistrate of Carthage and attempted to reform its finances. Accused by Rome of conspiring with the Seleucid king Antiochus III, he fled into exile, served briefly as a naval commander for the Seleucid Empire, and finally committed suicide in 183 BCE rather than be handed over to Rome. Scipio Africanus himself died a few months later, in the same year.

The Third Punic War (149–146 BCE)

For fifty years after Zama, Carthage recovered slowly, paying off its indemnity and rebuilding its economy. To the Romans, however, Carthage remained an object of dread and hatred. The senator Cato the Elder ended every speech, whatever its subject, with the words Carthaginem delendam esse — “Carthage must be destroyed.” In 149 BCE, the Romans manufactured a pretext for war and sent an army to Africa. Carthage, hoping to negotiate, agreed to surrender its arms. The Romans demanded that the city itself be demolished and that the population move inland. The Carthaginians refused, and endured a desperate three-year siege of their own city.

The final assault, in 146 BCE, was led by Scipio Aemilianus, the adopted grandson of Scipio Africanus. After six days of street fighting, Roman soldiers broke into the citadel. The last defenders refused to surrender. According to tradition, the city was set on fire, and Scipio stood watching the flames and weeping. He repeated a line from Homer: A day will come when sacred Troy shall perish, / and Priam and his people shall be slain. Rome had destroyed its rival utterly. The 50,000 surviving inhabitants were sold into slavery, the city was razed, and the territory was declared the Roman province of Africa.

Carthage was never rebuilt, and its destruction became, for the Romans, a source of uneasy pride. The city that had nearly destroyed them was gone. The Mediterranean, for the first time, was a Roman lake.

The Conquest of the Mediterranean

The same year that Carthage fell, the Romans also destroyed Corinth, the great Greek city that had revolted against Roman rule. Greece became the province of Macedonia. Within a single generation, Rome had conquered the entire Mediterranean basin, from the Atlantic to the Euphrates, from the Sahara to the North Sea. The wealth that poured in from these conquests transformed Roman society, dissolved the old citizen-farmer-soldier ideal, and set in motion the political crisis that would lead to the fall of the Roman Republic.
