For the past five hundred years, Europe has been the nexus of global culture and power. But throughout most of that history, most European countries have also been volatile and unstable—some even ground zero for catastrophic wars. As Friedman explores the continent’s history region by region, he examines the centuries-long struggles for power and territory among the empires of Spain, Britain, Germany, and Russia that have led to present-day crises: economic instability in Greece; breakaway states threatening the status quo in Spain, Belgium, and the United Kingdom; and a rising tide of migrants disrupting social order in many EU countries. Readers will gain a new understanding of the current and historical forces at work—and a new appreciation of how valuable and fragile peace can be.
