The Black Book of Communism is the first fundamental reference publication devoted to the study of the crimes of communist regimes that existed in the twentieth century. An international team of historians has done a tremendous amount of work, bringing together all the information about crimes committed under the flag of communism in many countries and on different continents. In this case, not only numerous testimonies and memories of eyewitnesses were used, but also materials from previously inaccessible archives. The book offered to the reader’s attention has already been published in many European countries. It is serious, large-scale, densely packed with facts, many of them are unique in their novelty, sometimes improbability. This is a kind of study about the cancer of Bolshevism, which mercilessly destroyed generation after generation all over the world and, above all, in Russia. The book was created by foreign historians. It's a pity that they are not Russian. But it’s remarkable that the study is published in a Russian edition. What kind of phenomenon is Bolshevism, founded by V. Ulyanov in 1903? Lenin at the beginning of the century pathetically exclaimed: “Give us a party of revolutionaries, and we will turn Russia over!” Turned it over. They turned it upside down. What did you get? Nothing, but we lost a whole century. They are the same century behind civilized countries. Tens of millions of people were killed. The country is poor, backward, the nation is biologically degenerating. And the prospects for recovery of the country and nation are by no means rosy. Why? Because our society, while not yet mortal, is still extremely poisoned by lies. We still continue to live in some kind of nightmare. We are fighting for freedom, but we live like a Soviet. The most terrible thing that exists in this world is the perversion of beauty. The Bolshevik regime was born out of revolutionary determination, verbally inspired by humanist ideals. Leninists were convinced that only violence is the universal and only means of realizing these ideals. Bolshevism and fascism are two sides of the same coin. Medals of universal evil.
