Analysis of information sources in references of the Wikipedia article "Mortes em massa em Estados comunistas" in Portuguese language version.
Communist regimes have been responsible for this century's most deadly episodes of mass killing. Estimates of the total number of people killed by communist regimes range as high as 110 million. In this chapter I focus primarily on mass killings in the Soviet Union, China, and Cambodia - history's most murderous communist states. Communist violence in these three states alone may account for between 21 million and 70 million deaths. Mass killings on a smaller scale also appear to have been carried out by communist regimes in North Korea, Vietnam, Eastern Europe, and Africa.
