Correct Answer: Vladimir the Great
Vladimir the Great was the Grand Prince of Kiev from 980 until the day he died in 1015. Although he was not the first to introduce Christianity into the Kievan Rus region (today Ukraine and Russia), he was the one who cemented it as the majoritarian religion in the area after his baptism in 988, ordering the end of paganism in the area (not without certain opposition). He unified most of this region unider his mandate.
As for the reason he chose Orthodox Christianity, it is somewhat shrouded in legend. The popular tale says that he sent emissaries to learn about the religions of neighboring.

As for the more historically accurate version, it is said that he converted in part as part of a military pact.

During the plague, many believed that if they let immigrants into their nation, a major outbreak could occur. However, nearly all places in the world were affected by the disease anyways. (Except for American Samoa, who refused to let anyone on the island)
