The baptism of Rus is one of the most important cultural events in the history of Ancient Rus. It put an end to the pagan and the beginning of the Christian history of Russia. The baptism of Rus took place at the end of the 9th century, the efforts that Prince Vladimir made during the establishment of Christianity as a state religion. The baptism of Rus did not pass painlessly for the Russian people and was associated with considerable resistance to the new Orthodox culture.
Initially, the way to Christianity to the very heart of Kiev's reign of Russia was laid by Princess Olga, the widow of the prince Igor, who was killed by the Drevlyans. Around 955, it was imbued with Christianity and was baptized in Constantinople. From there she brought Greek priests to Russia. However, Christianity was not widely spread then. The son of Princess Olga Svyatoslav saw no need for Christianity and continued to honor the old gods. The merit of establishing Orthodoxy in Russia belongs to one of his sons, Prince Vladimir.
