The Black Book Of Communism -

The Black Book of Communism: Crimes, Terror, Repression (1997) is a landmark study by European academics, led by Stéphane Courtois, that chronicles the human cost of communist regimes in the 20th century. It argues that mass state violence, including famines, executions, and forced labor, was intrinsic to these systems, estimating a total death toll of approximately 100 million. The work generated significant debate regarding its methodology and the comparability of its findings to other historical atrocities.
