Alexander the Great envisioned a city network designed to control “spear won” territory in the wake of his conquests. Alexander imagined a world bridging Greek and Asian cultures – a new era of globalization. He was willing to force whole populations across continents to this end, via city mergers, mass deportations, and resettlements. From its Macedonian foundations, the Hellenistic Age had urban roots. Greek economic influence spanned from Afghanistan to the Atlantic. Trade increased markedly, as did cultural exchange. There was unprecedented hybridization, closely reflected in city building. The urban form dwarfed what existed in the old poleis. Their geopolitical importance increased under territorial empires, the dominant form of statecraft. Cities managed flows of resources. They defended trading routes against nomads, projecting royal military power. Out of Alexander’s splintered empire, his namesake Alexandria was the closest realization of his global vision. There were darker sides to this: Alexandria was part of a system entailing political domination over peripheral zones.
