Performance theory is one of the methods that can explain dynamic and unpredictable social phenomena. The basics of our research are to be found in the artistic practices that destroyed previous classical patterns in art, while overcoming its boundaries. Accordingly, performance as a practical phenomenon has become the basis for a theoretical explanation of different political processes with carnival nature that influence and change social reality. This article proves that the Maidan in Kiev had a performative nature as well, which developped spontaneously due to its active involvement of the human body and the release of unconscious elements. It is claimed that the use of performative practices inside the Maidan allowed to overcome the totalitarian vertical logic of power, realizing democratic ideals and overcoming nihilism. Therefore, we suggest that performative theory can be applied to similar carnival political, social, and cultural phenomena, revealing their procedural and creative substance.
