The aim of the paper is the analysis of aesthetic theories of Russian Avant-garde and Post-avant-garde. The author claim that an essence of the avant-garde movement was the desire to form the world in accordance with an artistic project, which should have give a harmony and a beauty of the reality, but in fact was only a reflection of the will of power of soviets. In this perspective the Soviets and Soviet art, i.e. social realism were true successors of avant-garde and ones who continued its project instead of making it dead. The main thesis here is that social realism took over the avant-garde dream of a new world and made its own, what made avant-garde itself useless.
