The Russian Princess
Olga ruled Kiev and was baptized around the year 950. Her grandson Vladimir
was eventually baptized and summoned missionaries from the East to establish
churches and monasteries. Under the rule of Vladimir and later of his
son Yaroslav, the foundations of a Russian church were set in place. Much
later, after the fall of Constantinople
to the Turks in the sixteenth century, the church of Russia began to consider
itself the third vital center of historical Christianity and declared
Moscow "the third Rome."
