towering cedars. Egyptians, Sumerians, Assyrians, Babylonians and Hittites variously occupied the strategic ground of Syria during this period; the land between their various empires being marsh.
Eventually, the Persians took Syria as part of their hegemony of Southwest Asia; this dominion was transferred to the Ancient Macedonians and Greeks after Alexander the Great's conquests and the Seleucid Empire. The capital of this Empire (founded in 312 BC) was situated at Antioch, part of historical Syria, but just inside the Turkish border today. Pompey the Great captured Antioch in 64 BC, turning Syria into a Roman province. Thus control of this region passed to the Romans and then the Byzantines.
In the Roman Empire period, the city of Antioch was the third largest city in the empire after Rome and Alexandria. With an estimated population of 500,000 at its peak, Antioch was one of the major centers of trade and industry in the ancient world. The population of Syria during the heyday of the empire was probably not exceeded again until the 19th century. Syria's large and prosperous population made Syria one of the most important of the Roman provinces, particularly during the 2nd and 3rd centuries (AD).
The Roman Emperor Alexander Severus, who was emperor from 222 to 235, was Syrian. His cousin Elagabalus, who was emperor from 218 to 222, was also Syrian and his family held hereditary rights to the high priesthood of the sun god El-Gabal at Emesa (modern Homs) in Syria. Another Roman emperor who was a Syrian was Philip the Arab (Marcus Julius Philippus), emperor from 244 to 249.
Syria is significant in the history of Christianity; Saulus of Tarsus, better known as the Apostle Paul, was converted on the Road to Damascus and emerged as a significant figure in the Christian Church at Antioch in ancient Syria, from which he left on many of his missionary journeys.
