Aleppo is one of the oldest continuously inhabited cities in the world; it has been inhabited since perhaps as early as the 6th millennium BC. Excavations at Tell as-Sawda and Tell al-Ansari, just south of the old city of Aleppo, show that the area was occupied since at least the latter part of the 3rd millennium BC; and this is also when Aleppo is first mentioned in cuneiform tablets unearthed in Ebla and Mesopotamia, in which it is noted for its commercial and military proficiency. Such a long history is probably due to its being a strategic trading point midway between the Mediterranean Sea and Mesopotamia.
