Timothy Snyder, a Yale historian specializing in Eastern European history, presents a groundbreaking account of the lands between Berlin and Moscow where Nazi and Soviet violence converged. Between 1933 and 1945, some fourteen million people were deliberately murdered in this region through policies including the Ukrainian famine, the Great Terror, the Holocaust, and German anti-partisan warfare. Snyder argues that these killings, usually treated separately, should be understood as interconnected aspects of a single history. He shows how the Soviets' mass killings created conditions that the Nazis exploited, how Nazi and Soviet occupations alternated in ways that multiplied victimization, and how ideological conflicts played out through the bodies of the civilian populations caught between totalitarian powers. The book challenges Holocaust scholarship that treats it in isolation from Soviet crimes, while also resisting the equation of Nazi and Soviet violence that minimizes the Holocaust's distinctiveness. Snyder writes with moral clarity while maintaining scholarly precision, using detailed case studies to humanize statistics that would otherwise numb readers. This book permanently changed how scholars understand twentieth-century violence and is essential reading for anyone seeking to comprehend the darkest chapter of modern European history.
