This chapter discusses the economic developments occurring within the Ptolemaic empire (323–30 BCE), of which Egypt was the core province. It explores how state formation affected economic development and how Ptolemaic imperialism, demography, and the interaction between Egyptian and Greek social networks were factors of economic change and economic exploitation. After an overview of past and current approaches to the economy of the Ptolemaic empire and of the geography of the empire, it assesses the cost and benefits of military conquests and the management of migrations patterns and new settlements by the Ptolemies, who increased their revenues and reduced the cost of their army through land allotments to cleruchs. The political economy of the Ptolemies relied on a complex tax system, with some documents pointing to a centralized taxation of the provinces, and innovative but also unusual monetary policies, such as closed-currency system based on a lower weight standard than the Attic standard in Egypt, Cyprus, and Syria-Phoenicia. The chapter concludes with examples of the synergistic relationship between empire, warfare, and trade and between the public and private spheres of the economy, and sketches the purchasing power of different economic groups in Egypt.

This chapter explores the foundation of poleis beyond the capital cities, as well as the alteration and renaming of settlements as marks of imperialism. Rather than presenting an exhaustive survey, the authors emphasize the methodological issues faced by historians of identifying and assessing new settlements – Mairs by focusing on the historiography and archaeology of the early Seleucid Far East, and Fischer-Bovet by offering a typology of Ptolemaic settlements. Seleucid settlements in Bactria can only be understood as a continuation of Alexander’s settlement policy. Their strong military character shows the early Seleucid interest in Central Asia and is not representative of the empire as a whole. The Ptolemaic empire was also connected through a network of either new or transformed settlements, whose variety was adapted to each region and actively shaped by local populations. The existing urban and administrative networks, moreover, did not create the need for new poleis – and complementary explanation to the question raised by Clancier and Gorre in the same volume – but the new and altered settlements reflect the Ptolemaic strategy of combining Greek and Egyptian elements.

The Ptolemaic and Seleucid empires are usually studied separately, or otherwise included in broader examinations of the Hellenistic World. This book proposes a more dynamic comparison, with a particular, though not exclusive focus on the interaction of the royal centers with local populations and elites. Both political entities are approached as multiethnic empires whose resemblance and entanglement are sufficient to make comparisons meaningful. In the process of comparing them, differences and connections become more salient and better explained. We aim to explore the different structural capacities for, and levels of, integration that were either aspired to or achieved by the kings and populations of each empire.
