Antioch was founded near the end of the fourth century BC by Seleucus I Nicator, one of Alexander the Great's generals. The city's geographical, military, and economic location benefited its occupants, particularly such features as the spice trade, the Silk Road, and the Royal Road. It eventually rivaled Alexandria as the chief city of the Near East. The city was the capital of the Seleucid Empire until 63 BC, when the Romans took control, making it the seat of the governor of the province of Syria. From the early fourth century, the city was the seat of the Count of the Orient, head of the regional administration of sixteen provinces. It was also the main center of Hellenistic Judaism at the end of the Second Temple period. Antioch was one of the most important cities in the eastern Mediterranean half of the Roman Empire. It covered almost within the walls of which one quarter was mountain, leaving about one-fifth the area of Rome within the Aurelian Walls.
