Timothy Snyder

American historian of Eastern Europe who wrote Bloodlands — a history of the mass killing zones between Hitler and Stalin — and On Tyranny, a short guide to resisting authoritarianism.

Bloodlands: the region between Berlin and Moscow where both the Nazi and Soviet regimes conducted their mass killings — 14 million people killed, largely non-combatants. A comparative history that insists both regimes were responsible. Black Earth: the ecological and colonial logic of the Holocaust. On Tyranny: 20 lessons from the 20th century for resisting tyranny — a short, popular guide that sold millions after Trump's 2016 election.
