Carthage
A Phoenician merchant republic that built a maritime empire on trade and mercenaries before its long duel with Rome.
c. 814–146 BCE
The North African coast around modern Tunis, with an empire across the western Mediterranean—Sicily, Sardinia, and Iberia
Economy
Carthage grew rich as the commercial heir of Phoenicia, its wealth built on maritime trade, a fertile agricultural hinterland, and control of western Mediterranean metals—silver and tin from Iberia above all. Carthaginian estates practised advanced plantation agriculture, and the treatise on farming by Mago was so esteemed that the Roman Senate ordered it translated into Latin after the city's fall. The state minted coinage relatively late, relying long on Greek coin and bullion, and its immense revenues funded the mercenary armies and fleets on which its power depended.
Law
Carthage was governed as an oligarchic republic that Aristotle admired in his Politics as a well-balanced constitution, praising its mixture of monarchic, aristocratic, and popular elements. Executive power lay with two annually elected magistrates called suffetes, a senate of elders debated policy, and a powerful Tribunal of the Hundred and Four oversaw and disciplined the generals to guard against tyranny. Real influence rested with wealthy merchant and landowning families, and the failure of general and civil authority to align at times hampered the war effort against Rome.
Education
Carthaginian education is poorly documented, since almost all Punic literature was lost when Rome destroyed the city, but the elite were literate in the Phoenician script from which the alphabet spread across the Mediterranean. The great library of Carthage, dispersed after 146 BCE, and works like Mago's agricultural treatise testify to a written intellectual culture rooted in the Phoenician heritage of practical and religious learning. Knowledge of navigation, commerce, engineering, and religious ritual was cultivated among an aristocracy oriented toward trade and administration rather than the philosophical schools of the Greek world.
Army
Unlike Rome's citizen legions, Carthage fought largely with mercenaries and subject levies—Libyan infantry, Numidian light cavalry, Iberian and Celtic warriors, Balearic slingers, and war elephants—welded together by a professional officer class. This system produced the genius of Hannibal Barca, who crossed the Alps in 218 BCE and annihilated a Roman army at Cannae in 216 BCE through a masterful double envelopment still studied today. Yet reliance on hired troops proved a structural weakness: after the First Punic War unpaid mercenaries rose in the brutal Truceless War, and Carthage could not match Rome's bottomless reserves of citizen manpower.
Religion
Carthaginian religion was Phoenician, centred on the deities Baal Hammon and the goddess Tanit, worshipped with temples, priesthoods, and votive offerings across the Punic world. The most notorious and debated practice was child sacrifice at the sacred precinct known as the tophet, attested by Greek and Roman authors and by archaeological finds of urns holding cremated infants, though the interpretation remains contested among scholars. Religion permeated public life, from the naming of children and generals to the swearing of treaties, binding the far-flung Punic settlements to their mother city.
Architecture
Carthage was a densely built port city whose most remarkable feature was its artificial harbour complex: a rectangular commercial dock connected to an inner circular military harbour, the cothon, ringed with covered ship-sheds said to shelter more than two hundred warships. The city rose in tall multi-storey houses on the slopes below the fortified citadel of Byrsa and was protected by massive triple walls that resisted Roman siege for three years. After 146 BCE the Romans razed the Punic city, and much of what is known of its layout comes from archaeology and the later Roman colony built over it.
Trade
Trade was the lifeblood of Carthage, whose ships ranged from the Atlantic coasts of Iberia and Morocco to the eastern Mediterranean, dealing in metals, textiles, worked goods, salted fish, and the prized Tyrian purple dye. The explorer Hanno the Navigator reportedly sailed down the West African coast around the fifth century BCE, and Carthaginian treaties with Rome carefully partitioned commercial spheres in the western sea. So dominant was this maritime network that Carthage sought to make the western Mediterranean a Punic lake, a commercial supremacy that ultimately collided with Roman expansion.
Technology
Carthaginian technology was above all maritime and commercial: their shipwrights pioneered standardised, mass-produced warship construction, and a wrecked Punic vessel found off Sicily bore assembly marks showing prefabricated, interchangeable parts. Their circular military harbour was a feat of naval engineering, and Punic expertise in agriculture, surveyed and preserved in Mago's treatise, influenced Roman farming for centuries. Skilled in metallurgy, dyeing, and navigation—using the stars and detailed sailing knowledge to reach distant Atlantic ports—the Carthaginians embodied a practical, seaborne technical culture inherited from Phoenicia.
