Abstract

Despite the continued interest of researchers from different eras to the problem of the emergence and spread of heretical teachings in Kievan Rus, a number of issues remain insufficiently covered. In particular, the issue of the origins and spread of those heretical teachings that contributed to the development of iconoclastic ideas is worthy of particular attention. In the proposed article, we will look at the most influential heretical currents that penetrated the territory of Kievan Rus with Christianity and began to spread, finding favorable conditions for its development here.
