You can’t understand the war in Ukraine without knowing history

Timothy Snyder is the Levin professor of history at Yale University and the author of “The Road to Unfreedom” and “Bloodlands.” His updated audio edition of “On Tyranny” includes 20 new lessons about Ukraine.

Teaching a lecture class on Ukrainian history last fall, I felt a touch of the surreal. The war in Ukraine had been going on for half a year when I began. A nuclear power had attacked a state that had given up its nuclear weapons. An empire was trying to halt European integration. A tyranny was attempting to crush a neighboring democracy. On occupied territories, Russia perpetrated genocidal atrocities with clear expressions of genocidal intent.
