For thousands of years, humanity has lived in the power of myth and to this day participates in the mythmaking process. In its attempt to generalize a person's ideas about the world around him, to make it understandable, convenient, manageable and reasonable, myth assumes the fundamental properties of discourse. Political discourse is no exception, in which the communicants appear as collective, carefully planned mythologized subjects ("power", "voters", " people", etc.). Politicians in their speeches turn to various communicative strategies and manipulations to achieve their political objectives. Political myth aims not only to justify a certain course of events, to ensure the people's faith in the right direction of political actions, but also to create memorable, vivid images of participants in the political process: facts from the life of a politician, the image of state policy in general.
