Carthage

814 BCE - 698 CE

Founded c. 814 BCE

Phoenician and Roman city

The Byrsa Citadel and Early Urban Development

At the heart of Punic Carthage stood the Byrsa, a high citadel that served as the city's final defensive stronghold during the Roman siege of 146 BC. Archaeological evidence indicates the city was a 'creation ex nihilo' founded on virgin land, with its earliest seventh-century nucleus covering roughly 10 hectares near the coast. The Byrsa heights were not only fortified but also housed luxury residences and significant religious structures, including the Temple of Eshmun, which was reached by a monumental stairway consisting of sixty steps.

Punic Agricultural Science and the Mago Treatise

Carthaginian prosperity was deeply rooted in advanced agricultural sciences, which adapted Eastern Mediterranean techniques to African conditions. This expertise was codified in a 28-volume Punic treatise by Mago, a retired general, which covered topics ranging from viniculture and olive grafting to farm management. Although the original Punic text is lost, its influence was so significant that the Roman Senate ordered its translation into Latin. The surrounding countryside, or Chora, was characterized by sophisticated irrigation channels, lush orchards, and market gardens that rivaled the agricultural output of Rome.

The Tophet and the Debate Over Child Sacrifice

Located south of the citadel near the harbors, the tophet was a sacred enclosure containing thousands of stone stelae and urns. Excavations in the 1920s revealed a mixture of animal and infant bones, sparking a long-standing scholarly debate. While some researchers interpret the site as a standard cemetery for infants who died of natural causes, others point to epigraphic evidence and the specific mixing of animal and human remains as proof of ritual child sacrifice. Recent studies and ancient Greco-Roman accounts increasingly support the consensus that child sacrifice was indeed practiced by the Carthaginians.

The Byzantine Exarchate and Final Destruction

In 533–534 AD, the Eastern Roman Empire reclaimed Carthage from the Vandals, establishing it as the capital of the Exarchate of Africa. As a western bulwark of Byzantine power, the city remained a significant cultural and economic hub until the late seventh century. However, following the Battle of Carthage in 698 AD, Umayyad forces captured the city. To prevent a Byzantine reconquest, the victors implemented a scorched earth policy, tearing down the city walls, cutting off the water supply from the aqueducts, and rendering the famous harbors unusable.

The Punic Mixed Constitution

Aristotle praised the Carthaginian government as an excellent 'mixed constitution' that balanced elements of monarchy, aristocracy, and democracy. The state was led by two elected magistrates called suffets who held civil power for one-year terms, while military generals were elected separately to prevent tyranny. A council of elders, similar to the Roman Senate, advised the suffets, and a powerful tribunal of 104 judges oversaw the conduct of generals. This system was remarkably stable, with Aristotle noting that Carthage had never suffered a significant rebellion or the rule of a tyrant.

Engineering of the Massive Defensive Circuit

The city was protected by an extensive defensive system totaling approximately 33 to 37 kilometers in length. While the coastal sections were less formidable due to Carthaginian naval supremacy, the landward defenses across the western isthmus were exceptionally massive and never breached. These land walls were reported by ancient authors to reach thicknesses of nearly 10 meters and heights exceeding 13 meters. To the west, the defense was further reinforced by three parallel walls, ensuring the city remained one of the most secure urban centers of the Hellenistic period.

Scale of Punic Industrial Manufacturing

Carthage functioned as a major manufacturing center, with specialized industrial zones located north and west of its harbors. The city supported diverse crafts, including metalworking for weapons and domestic tools, pottery kilns producing Greek-style earthenware, and a textile industry famous for its 'Phoenician purple' dye derived from murex shells. During the Third Punic War, the city's industrial capacity was so great that it reportedly produced 140 shields, 300 swords, 500 spears, and 1,000 catapult missiles daily, while simultaneously building 120 decked ships in just two months.

Roman Reconstruction and Imperial Scale

Following the total destruction of Punic Carthage in 146 BC, the site was eventually rebuilt as a Roman colony by Julius Caesar and Augustus. This new city, Roman Carthage, became the capital of the province of Africa and grew to be the second-largest city in the western Roman Empire, with a peak population estimated at 500,000. The Roman engineers leveled the Punic ruins to create a massive new forum on the Byrsa hill, supported by foundation piles that preserved the Punic residential layers beneath them, and constructed major monuments including a large amphitheater.
