Phoenician and Greek Libya
The Phoenicians were the first to establish trading posts in Libya, when the merchants of Tyre (in present-day Lebanon) developed commercial relations with the Berber tribes and made treaties with them to ensure their cooperation in the exploitation of raw materials. By the 5th century BC, the greatest of the Phoenician colonies, Carthage, had extended its hegemony across much of North Africa, where a distinctive civilization, known as Punic, came into being. Punic settlements on the Libyan coast included Oea (later Tripoli), Libdah (later Leptis Magna) and Sabratha. These cities were in an area that was later called Tripolis, or "Three Cities", from which Libya's modern capital Tripoli takes its name.
In 630 BC, the Ancient Greeks colonized Eastern Libya and founded the city of Cyrene. Within 200 years, four more important Greek cities were established in the area that became known as Cyrenaica: Barce (later Marj); Euhesperides (later Berenice, present-day Benghazi); Taucheira (later Arsinoe, present-day Taucheria); Balagrae (later Bayda and Beda Littoria under Italian occupation, present-day Bayda);and Apollonia (later Susa), the port of Cyrene. Together with Cyrene, they were known as the Pentapolis (Five Cities). Cyrene became one of the greatest intellectual and artistic centers of the Greek world, and was famous for its medical school, learned academies, and architecture. The Greeks of the Pentapolis resisted encroachments by the Ancient Egyptians from the East, as well as by the Carthaginians from the West, but in 525 BC the Persian army of Cambyses II overran Cyrenaica, which for the next two centuries remained under Persian or Egyptian rule. Alexander the Great was greeted by the Greeks when he entered Cyrenaica in 331 BC, and Eastern Libya again fell under the control of the Greeks, this time as part of the Ptolemaic Kingdom. Later, a
