The spread of Christianity in the Northern Black Sea Region was a continuation of the vector of cultural expansion into this region, outlined in Antiquity and opposing the region’s stable geopolitical ties in the latitudinal direction, with the steppe world of the nomads of Eurasia. The stages of this process were: the Great Greek colonization on Pontus Euxinus; the spread of Pax Romana to the territory of Crimea; the Christianization of the region and the strengthening of Byzantium in the Northern Black Sea Region through an alliance with the Khazaria and the creation of the Klimata-Cherson thema; finally, the emergence of Italian trading posts and the emergence of Genoese Gazaria. The success of the Christian mission of Byzantium would not have been possible without the oncoming movement from the north, which determined the reception of the Byzantine civilization by Rus’-Russia and predefined the geopolitical contours of the modern world. In the opposite direction there was an advance to the south of Rus’ and the formation of the path “from the Varangians to the Greeks”, sea voyages of the Rus’ princes to Constantinople, the capture of Korsun’Cherson by Vladimir the Saint and the baptism of Rus’, the inclusion of Russia in the system of the Byzantine church administration. At the new historical stage, after the fall of Byzantium, the role of the Christian Orthodox empire passed to Russia, and the processes of intercivilizational interaction in the region changed their vector. But even in the new conditions, the meridional dimension remains incomparably more important than the latitudinal dimension: a fact that determines the future geopolitical perspective.
