It should be noted that any systematization should be based on homogeneous principles – criteria of one level. At the basis of the classification under consideration, all criteria (definitives) are in different planes. How can one compare the “historical approach” of a researcher with the idea of the modernization functions of the revolution or the basic principle of the model? You can only compare comparable categories. For example, those who invest in modernization functions and regressive functions, who place the principle of the role of state structures or demos organization at the forefront of revolution, those with a historical or mathematical approach (or any other), those who use structural-functional analysis and those who, for example, are repelled by form, quantity and strength, etc.

In many ways, the essence of the approaches of the entire XX and beginning of the XXI centuries. It boils down to the development of a theory of the revolution of Marxism or to the desire to oppose something to this theory. On the first side, revolutions are considered only in connection with a change in formations, on the second side, any massive radical forms of protest and coup d’etat fall into the revolution. It should be recognized that the Marxist approach is still more systematic and holistic, which constantly attracts adherents, and many of its provisions, one way or another, have been borrowed to this day. “The Marxist theory of society, often refined to the theory of revolution, remains one of the most stimulating models for the analysis of revolutionary processes of transformation” – a conclusion that many researchers have come to. The Marxist approach is more systemic, but sins with schematism. The three biggest shortcomings are the understanding of the revolution as a mandatory transition between formations, the inevitability of the proletarian revolution, which should lead to the emergence of the last formation (higher), economic determinism. The disadvantages of all opponents are more numerous. The lack of a clear definition of revolution (which allows “ripping” any riot, any significant social protest, ordinary coup d’etat into the term “revolution”), the causes of the emergence, the confusion of the causes of the revolution and what became the “trigger” – the reason for the first mass demonstrations.

A lot of research and criticism led to the fact that, regardless of the vulnerability of many of the formulations and provisions that came in the XX century, and were developed in its first third, in the subsequent XX century introduced little new. Most attempts to create something new lead to the same situation. The situation that has developed since the 80s. XX century can be classified as a methodological crisis: existing methodologies and research methods do not satisfy, new ones do not appear. The shortage of new developments leads to the fact that analytical models of researchers, the same definitions, and schemes with small modifications wander from research to research.

If we summarize the current state of the theory of revolution, today there is no single definition of revolution that is satisfactory and accepted by the majority. Not a single concept gives an answer to why revolutions are characteristic only of the era of capitalism and are unknown until the first bourgeois revolutions. There is no agreement on the causes or consequences of revolutions. The problem of typology (classification) of revolutions is one of the most difficult to develop a theory of revolution, where two extremes dominate: the simple division of revolutions into “western” and “eastern” or the promotion of a whole set of types, types and subspecies that suffer from a methodological point of view and in no way do not bring final clarity to the subject under study, in addition, a characteristic feature is the attempt to modernize various established theories and approaches and their resuscitation. The new generation of researchers in the theory of revolution will have to answer all the same questions and to break the movement in the circle of the same ideas and concepts, to look for fundamentally different approaches.
