4. Russia
Total Christian Population: 105 220 000
The Christian influence in Russia showed the intact relationship between the ruler and his tribe. The conversion of Vladimir, the Prince of Kiev, to Christianity around 988 was the beginning of the religious history of Russia. Gerald Bray, in Christianity of Soviet Russia, stated that the event was common to barbarian tribes in Northern Europe in which the conversion of the entire tribe began after the baptism of its ruler. Thus, Russian Christianity has been a state religion.
