"Pax Romana to Pax Medieval: Economic Continuities and Changes" by Ryan Evans explores the profound economic transformations that took place between the Roman Empire and the rise of medieval Europe. Through a detailed analysis of key economic structures and systems, the book traces how agricultural practices, trade, labor, taxation, and political economy evolved from the stability of the Roman Pax Romana to the dynamic yet fragmented economic world of the Middle Ages. It examines the continuities in agricultural innovations, the rise of new trade routes, and the persistence of old systems like feudal land tenure and tribute. At the same time, the book highlights the significant changes brought on by the decline of Roman centralization, the emergence of feudalism, and the gradual shift to a market-driven economy. Through the lens of historical context and economic theory, Evans delves into how these transformations laid the groundwork for the development of modern capitalism and shaped the social, political, and economic landscape of Europe for centuries to come.
