The purpose of the monograph presented to the reader is to reconstruct the strategic guidelines of the political and religious activities of Alexander Nevsky in the context of world civilizational and geopolitical transformations. At the same time, the course of the historical process within the framework of various civilizational communities and their interactions is examined. An integrated version of the history of the century is proposed, as a collision of various variants of religious projects. The results of the study consist in substantiating the likelihood of Alexander Nevsky putting forward and implementing a “soft power” strategy, consisting of plans to remove threats from the east and expand the borders of the Christian civilizational area through the spread of Christianity among the Mongols. The theoretical significance of the study is determined by rethinking Alexander Nevsky’s strategy as an active policy of religious ideological influence. The practical significance of the work is associated with the potential for the formation of a new cultural policy of Russia in the eastern direction.
