To stabilize his conquests strategically, and to unify his new kingdom culturally, Alexander III founded a number of Greek-speaking eponymous Alexandrias. There is some dispute over exactly how many new cities he founded in all. But the first, named after Alexandroupolis in northern Greece was in Africa, in the Nile delta near the river's outlet into the Mediterranean. ‘Alexandria’ describes the history of this famous city, the first and perhaps the most important of the Alexandrias. It was the first Hellenistic polis, just as Alexander may be said to be the first Hellenistic king. Unfortunately, most of Hellenistic Alexandria is either now obliterated on land, or submerged.
