History of immorality in politics (In Russia: Nechayev - Lenin - Stalin - and others later) "Politics and morality are incompatible," "Politics is a dirty business ... it has always been and so it will" - such opinions are very often you can hear from a variety of people. More educated people can add that it was at least from the time of Machiavelli. However, in the early XX century, the word "Machiavellianism" was considered a dirty word synonymous with immorality in politics. When and who made politics as a dirty business? The author believes that in Russia the theoretical and practical bases of amorality in the policy were laid down in the 1870s by Russian revolutionary Sergey Nechayev (prototype of the protagonist in the novel "Demons" ("The Possessed") by Dostoevsky). Later Vladimir Lenin after 1917 fully embodied the "revolutionary catechism" (by Nechayev) in life and in real politics. Later amoral principles also captured global policies too. It is still going on. Of course, it would be wrong to say that modern Russia is the same "evil empire" (in the words of Ronald Reagan), what was the Soviet Union during the Lenin and Stalin. The author does not say it, but only considers the history of immorality in the political struggle in Russia in the late XIX - early XX century. Another thing is that the "birthmarks" of the Bolshevik ideology (in the form of nostalgia for empire and some sympathy for Stalinism) exist in some part of the Kremlin's power elites till now.
