"The planned, designed, institutional reorganization of urban populations, together with a systematic and rationally-articulated thinking about cities, were, for whatever reason, characteristic of the Greek world since the archaic period. But nothing matches the royal synoikisms of the early Hellenistic period for scale of ambition, coherence of vision, and on-the-ground disruption. In this impressive and considered book, Ryan Boehm investigates such consolidations of existing Greek poleis into new or expanded mega-cities by the warlords, kings, and dynasts of the early Hellenistic period. . . . Boehm splendidly makes the case for his topic."
