The series "Baptism of Rus" is a documentary project dedicated to the history of Christianity in Russia. It covers a vast period - from Rurik and Prince Vladimir to the present day - and explains how and for what reasons the belief in Jesus Christ and the one Lord replaced the Slavic polytheism. It turns out that the spread of Christianity is directly related to geopolitical issues. Dynastic marriages, advantageous international alliances, and bloody wars have influenced the beliefs of the people.
