The name "Syria" historically referred to a wider region, broadly synonymous with the Levant, and known in Arabic as ''al-Sham''. The modern state encompasses the sites of several ancient kingdoms and empires, including the Eblan civilization of the 3rd millennium BC. Aleppo and the capital city Damascus are among the oldest continuously inhabited cities in the world. In the Islamic era, Damascus was the seat of the Umayyad Caliphate and a provincial capital of the Mamluk Sultanate in Egypt.
