The Punic Wars were a trio of conflicts between the Roman Republic and the Carthaginian Empire fought from 264 to 146 BC. Over the course of forty-three years, these wars unfolded on land and sea across the western Mediterranean, along with a four-year revolt against Carthage.
The First Punic War began in 264 BC on the island of Sicily, sparked by Rome’s expansionist aims and Carthage’s determination to maintain control over the region. At the time, Carthage dominated the western Mediterranean with its powerful naval empire, while Rome—strong on land but lacking a navy—was rapidly growing across Italy. The conflict was fought mainly in Sicily and surrounding waters, as well as in North Africa, Corsica, and Sardinia. After twenty-three years of war, Carthage was defeated in 241 BC, forced to pay heavy reparations, and compelled to cede Sicily, which became Rome’s first province. The aftermath also saw the outbreak of the Mercenary War, an internal revolt against Carthage.
The Second Punic War began in 218 BC and is best known for the Carthaginian general Hannibal, who led his army across the Alps to invade Italy. His campaign achieved major early victories and continued in Italy for fourteen years before ultimately withdrawing. Fighting also spread through Iberia, Sicily, Sardinia, and North Africa. Rome launched a successful invasion of Carthaginian territory in Africa in 204 BC, prompting Hannibal’s return. He was defeated at the Battle of Zama in 202 BC, after which Carthage sued for peace. The treaty of 201 BC stripped Carthage of its overseas lands and parts of its African territory, imposed a massive indemnity, sharply reduced its military capacity, and forbade it from waging war without Roman approval—effectively ending Carthage as a military rival.
The Third Punic War began when Carthage, trying to resist Numidian aggression in 151 BC, gave Rome a pretext to declare war in 149 BC. Fought entirely on Carthaginian soil in modern-day Tunisia, the conflict centered on the siege of Carthage. In 146 BC, the Romans captured and destroyed the city, killing or enslaving its inhabitants and razing it to the ground. Its territory was absorbed into the new Roman province of Africa. The remains of ancient Carthage still stand east of modern Tunis on the North African coast.
The most dependable ancient source on the Punic Wars is the historian Polybius (c. 200–c. 118 BC), a Greek taken to Rome as a hostage in 167 BC. His major work, The Histories, was written sometime after 146 BC. Polybius approached history analytically, interviewing participants from both sides whenever possible. He also accompanied his friend and patron, the Roman general Scipio Aemilianus, during the Third Punic War in North Africa. Although modern scholars note that Polybius tended to portray Scipio and his family too favorably, his writings are still regarded as largely trustworthy. Craige Champion calls Polybius “remarkably well-informed, industrious and insightful,” while Adrian Goldsworthy states that Polybius’s version “is usually to be preferred when it differs with any of our other accounts.” Despite his pro-Roman perspective, his work is generally considered objective, and modern reconstructions of the wars rely heavily on interpretations of his narrative.
Another major source—especially where Polybius’s text is missing—is the Roman historian Livy. Livy drew extensively from Polybius but organized his material more systematically, adding greater detail about Roman political life while expressing an openly pro-Roman stance. His descriptions of military events, however, are often inaccurate. Goldsworthy remarks that Livy’s reliability is “often suspect,” and Philip Sabin characterizes him as exhibiting “military ignorance.”
Several later ancient accounts survive, though typically in fragments or summaries. Historians also consult Roman annalists, some contemporary; the Sicilian Greek writer Diodorus Siculus; and later authors such as Plutarch, Appian, and Dio Cassius. No Carthaginian-authored primary sources have survived, though traces of Carthaginian perspectives—such as those of Philinus of Agrigentum—appear indirectly in pro-Roman writers, particularly Polybius. Additional evidence comes from coins, inscriptions, archaeological remains, and experimental reconstructions such as the trireme Olympias.
Background and Origin

For a century prior to the First Punic War, the Roman Republic had been expanding aggressively across southern Italy. By 270 BC, after the Pyrrhic War ended, Rome controlled all of peninsular Italy south of the Arno River. Meanwhile, Carthage—based in modern Tunisia—had built a powerful maritime empire stretching across southern Iberia, parts of North Africa, the Balearic Islands, Corsica, Sardinia, and the western half of Sicily.
Starting in 480 BC, Carthage fought several inconclusive conflicts with the Greek city-states of Sicily, led by Syracuse. By 264 BC, Carthage dominated much of Sicily, particularly the southern and western regions. At this point Rome and Carthage were the two leading powers of the western Mediterranean. Relations between them had long been peaceful, supported by formal alliances in 509 BC, 348 BC, and around 279 BC, as well as strong commercial ties. During the Pyrrhic War (280–275 BC), Carthage even supplied Rome with resources and at least once lent its fleet to transport Roman troops.
However, as the two states’ spheres of influence drew closer, the likelihood of conflict grew. Ultimately, they drifted into war more through miscalculation than deliberate policy, with neither side anticipating a long or difficult struggle.
Opposing Forces
Armies
Roman citizens who met a property requirement were liable for military service, typically serving as infantry, while wealthier men provided cavalry. During wartime, Rome customarily raised two legions, each consisting of 4,200 infantry and 300 cavalry. About 1,200 infantry—usually younger or poorer men—served as velites, lightly armed skirmishers equipped with javelins, a short sword, and a large round shield. The remaining infantry formed the heavy legionary ranks, armed with body armor, large shields, and short thrusting swords. They were arranged into three lines: the first carried both javelins and weapons for close combat, while the second and third bore thrusting spears. Roman armies typically fought in relatively open formations. Each year, two consuls were elected as Rome’s senior magistrates, and during war each commanded an army composed of a Roman legion paired with a similarly structured allied Italian legion, the latter usually providing more cavalry.
Carthaginian citizens served only when Carthage itself was threatened. When they did, they fought as heavily armored infantry with long spears, though they were often poorly trained and disciplined. Under most circumstances, Carthage relied on foreign troops. Many came from North Africa—commonly referred to as Libyans—and included close-order infantry, javelin-armed skirmishers, heavy shock cavalry, and light cavalry, especially Numidians. Both citizen infantry and close-order African troops fought in phalanx formation. Carthaginian forces also included Iberian and Gallic infantry and cavalry, known for fierce charges but limited stamina in prolonged engagements. Slingers from the Balearic Islands and war elephants—then native to North Africa—were frequently employed.
Campaigning typically involved garrison duty, foraging, and land blockades. Armies consumed vast amounts of food and supplies, which could be brought by pack animals, stored in depots, or gathered locally through foraging. Superior cavalry made it easier to protect or disrupt these operations. Large forces relying on local resources needed to move often to avoid depleting the countryside.
Before battles, armies commonly camped 2–12 km (1–7 miles) apart for extended periods, sometimes drawing up in battle order daily. If a commander felt disadvantaged, he could withdraw without fighting, making it difficult to force engagement. Forming for battle was a slow, deliberate process. Infantry formed the center of the line, skirmishers deployed in front, and cavalry held the flanks. Many battles were decided when one side’s infantry was outflanked or enveloped.
Navies
Quinqueremes—large, powerful warships—served as the backbone of both Roman and Carthaginian fleets. Polybius frequently uses the term simply to mean “warship.” A typical quinquereme carried a crew of 300: 280 rowers and 20 deck personnel, along with about 40 marines, a number that could rise to 120 before battle.
In 260 BC, Rome resolved to build its own fleet and modeled its first quinqueremes on a captured Carthaginian ship. Lacking experience, the Romans produced heavier and less maneuverable vessels, and their rowers required extensive training to match Carthaginian skill. To offset this disadvantage, the Romans introduced the corvus, a boarding bridge with a heavy spike that could latch onto enemy decks, allowing Roman infantry to board and seize ships rather than rely on ramming.
Warships were equipped with bronze rams, but by this period boarding actions had become more common as larger ships lost the speed and agility needed for effective ramming. The corvus reinforced this trend but also added weight to the bow, reducing stability and maneuverability. In rough seas it was unusable, and Rome eventually abandoned it partway through the First Punic War.
