The Punics, (from Latin pūnicus meaning Phoenician) were a group of Western Semitic speaking peoples originating from Carthage in North Africa who trace their origins to a group of Phoenician and Cypriot settlers, but also to North African Berbers. Punics were probably a biological and cultural mix of Berbers and Phoenicians. Contrary to 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 coastal regions of the Maghreb, Tripolitania, 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 Islands, the Canaries, and West Africa. Famous technical achievements of the Punic people of Carthage are the development of uncolored glass and the use of lacustrine limestone to improve the purity of molten iron.
