The Punics (from Latin pūnicus, pl. pūnici) were a group of western Semitic-speaking peoples from Carthage in North Africa who traced their origins to a group of Phoenician settlers, but also to North African Berbers. Punics were probably a mix of Berbers and Phoenicians in terms of culture and ancestry. Unlike other Phoenicians, Punics had a landowning aristocracy who established a rule of the hinterland in Northern Africa and trans-Sahara traderoutes. In later times one of these clans conquered a Hellenistic-inspired empire in Iberia, possibly having a foothold in western Gaul. Like other Phoenician people their urbanized culture and economy was strongly linked to the sea. Overseas they established control over some coastal regions of Berber North Africa like modern-day Tunisia and Tripolitania (modern-day Libya), Sardinia, Corsica, Sicily, the Baleares, Malta, other small islands of the Western Mediterranean and possibly along the Atlantic coast of Iberia, although this is disputed. In the Baleares, Sardinia, Corsica and Sicily they had strong economic and political ties to the independent natives in the hinterland. Their naval presence and trade extended throughout the Mediterranean to the British Isles, the Canaries, and West Africa. Famous technical achievements of the Punic people of Carthage include the development of uncolored glass and the use of lacustrine limestone to improve the purity of molten iron.
