The article examines the development of politicized Shiite Islam in Iran as a type of autopoiesis (N. Luhmann) of this religious tradition. The topic arises from the actualization of the influence of religion on the life of a number of societies that have relied on technological modernization, as well as the importance that the topic of the optimal combination of modernization and traditional values is acquiring today. The purpose of the study is, based on an analysis of the activities of the Shiite clergy, to characterize the uniqueness of the revaluation of the values of Iranian society in the course of the development of modern philosophy and ideology of Shiism. The objectives of the study were: 1) to systematize the existing scientific approaches to the process of politicization of Shiism in the second half of the 20th – early 21st centuries; 2) consider the connection between political processes and the specific theology of Shiism; 3) reveal the dynamics of the relationship between the values of tradition and modernization in the teachings of Shiite religious figures; 4) clarify the specificities of the stages of influence of Imami Islam on the religious and political life of modern Iran. The research was based on theological and scientific writings of Islamic spiritual leaders, their opponents and followers. The key method used was historical-genetic, which made it possible to analyze the formation of Shiism in Iran in the historical and cultural context; and comparative, with the help of which the specifics of the various stages of the autopoietic formation of Iranian Shiism against the background of other denominations of Shiism and Islam in general were clarified. It has been proven that consideration of the path of development of the philosophical and ideological aspects of Shiism theology from the perspective of N. Luhmann's theory makes it possible to trace not only the external, but also the autochthonous foundations of the complex reverses of this religious model of self-awareness of society; as well as identify and characterize the functional specificity and dynamic characteristics of the process of politicization of Shiism in Iran. In modern Iran, theology influences the consciousness of believers, and, as a consequence, social and political processes, and not vice versa, as is commonly believed in relation to modern societies. The role of Imami Islam (Shiites) in the formation of values and behavioral attitudes during the actual structuring of relations in society turns out to be key for Iran. At the same time, however, this theology contains the potential for historical change: the very theological system changes, starting from its own concepts and transforming them. This constructivist approach turns out to be compatible with the emphasis on traditionalism. The logical possibility of such collaboration in building a new type of society is justified within the framework of the development of the theory of legal guardianship.
