Fear has long been a driving force - perhaps the driving force - of world history: a coercive tool of power and a catalyst for radical change. Here, Robert Peckham traces its transformative role over a millennium, from fears of famine and war to anxieties over God, disease, technology and financial crises. In a landmark global history that ranges from the Black Death to the terror of the French Revolution, the AIDS pandemic to climate change, Peckham reveals how fear made us who we are, and how understanding it can equip us to face the future.
