Timothy Snyder’s work examines the problem of tyranny from every possible angle, drawing on examples from 20th-century history — unusually rich in material of this kind. Who becomes a tyrant, and who is to blame? Why do millions of people endowed with freedom of choice suddenly begin to obey someone else’s will and meekly carry out any commands, even when it threatens their lives and the lives of their loved ones? Can the appearance of tyrants be predicted, and why is it important to protect public institutions? What danger do words and symbols contain, where is the line between democracy and dictatorship, and how — if at all — can one fight a tyrant? But most of all, this book offers twenty specific conclusions that we must draw from the cruel lesson of history so we don’t repeat the mistakes of the past.
