This became clear after a while. The Bolsheviks eliminated the achievements of the February democratic revolution and imposed a crude military dictatorship on Russia. And they turned the Russian peasants into state serfs - kolkhozniki. Voslensky convincingly showed that in its political and social formation, Bolshevik Russia most resembled ... the medieval bureaucratic Chinese empire.
You will laugh - but when publishing many works of Marx and Engels, the Russians carefully extinct from them the mention of the Middle Ages Chinese method of production. Too many parallels with their Soviet state arose.
