The article presents the results of a long-term study of protest as a cultural phenomenon, the transformation of values, realized in the activities of the best people of the planet and their followers. These values have absorbed the experience of many generations and the behavior of people defending the rights of an individual to dignity, equality before the law, fair attitude, freedom of thought. In the history of the development of political thought, values have formed that constitute the core of civil culture. The genesis of the birth of the nucleus of civil culture from the thinkers of Antiquity, ideologists of nonviolent resistance, leaders of the French bourgeois revolution, activists of the “new left” movement to the protests of our time is shown. The basis for updating the protection of these values is the socio-political situation, characterized by the divergence of interests of civil society and ruling political groups. The values of the core of civil culture (freedom of speech, freedom of conscience, freedom of assembly, human rights) acquire an acute urgency in situations of power crisis. This is the time of the birth of new values that will mobilize new generations of protesters. Protest, as an act of protecting the values of the individual, is a measure of the level of development of political culture in the state. The protest — it's not just a mass exit of dissent on the area. This is an indicator of the level of self-awareness of citizens and the development of the political culture of society. The symbols of political protest actions are a special text that expresses the meanings of values. The authors present the results of a sociological study, which used comparative, value-semantic, interpretive approaches, studied the meanings and values of political protests of the 20th — early 19th centuries, analyzed visual and publicistic evidence of protest actions: photo and video materials, publications in the press.
