It's easy to think that ancient history is, well, ancient history—obsolete, irrelevant, unjustifiably focused on Greece and Rome, and at risk of extinction. In What Is Ancient History?, Walter Scheidel presents a compelling case for a new kind of ancient history—a global history that captures antiquity's pivotal role as a decisive phase in human development, one that provided the shared foundation of our world and continues to shape our lives today.

For Scheidel, ancient history is when the earliest versions of today's ways of life were created and spread—from farming, mining, and engineering to housing and transportation, cities and government, writing and belief systems. Transforming the planet, this process unfolded all over the world, in Eurasia, Africa, and the Americas, often at different times, sometimes haltingly but ultimately unstoppably. Yet it's rarely studied or taught that way.

The time has come, Scheidel argues, to put the ancient world back together—by moving beyond the limitations of Greco-Roman "classics," by systematically comparing ancient societies, and by exploring early exchanges and connections between them. The time has come, in other words, for an ancient history for everyone.
