The Primary Chronicle reports that in the year 987, after consultation with his boyars, Vladimir the Great sent envoys to study the religions of the various neighboring nations whose representatives had been urging him to embrace their respective faiths.
The result is described by the chronicler Nestor.
Of the Muslim Bulgarians of the Volga the envoys reported there is no gladness among them, only sorrow and a great stench.
He also reported that Islam was undesirable due to its taboo against alcoholic beverages and pork.
Vladimir remarked on the occasion: "Drinking is the joy of all Rus'.
We cannot exist without that pleasure."
Ukrainian and Russian sources also describe Vladimir consulting with Jewish envoys and questioning them about their religion, but ultimately rejecting it as well, saying that their loss of Jerusalem was evidence that they had been abandoned by God.

His emissaries also visited pre-schism Latin Rite Christian and Eastern Rite Christian missionaries.
Ultimately Vladimir settled on Eastern Christianity.
In the churches of the Germans his emissaries saw no beauty; but at Constantinople, where the full festival ritual of the Byzantine Church was set in motion to impress them, they found their ideal: "We no longer knew whether we were in heaven or on earth", they reported, describing a majestic Divine Liturgy in Hagia Sophia, "nor such beauty, and we know not how to tell of it."
Vladimir was impressed by this account of his envoys.

In 988, having taken the town of Chersonesos in Crimea, he boldly negotiated for the hand of emperor Basil II's sister, Anna.
Never before had a Byzantine imperial princess, and one "born in the purple" at that, married a barbarian, as matrimonial offers of French kings and German emperors had been peremptorily rejected.
In short, to marry the 27-year-old princess to a pagan Slav seemed impossible.
Vladimir was baptized at Chersonesos, however, taking the Christian name of Basil out of compliment to his imperial brother-in-law; the sacrament was followed by his wedding to Anna.
Returning to Kiev in triumph, he destroyed pagan monuments and established many churches, starting with a church dedicated to St. Basil, and the Church of the Tithes (989).

Arab sources, both Muslim and Christian, present a different story of Vladimir's conversion.
Yahya of Antioch, al-Rudhrawari, al-Makin, Al-Dimashqi, and ibn al-Athir all give essentially the same account.
In 987, Bardas Sclerus and Bardas Phocas revolted against the Byzantine emperor Basil II.
Both rebels briefly joined forces, but then Bardas Phocas proclaimed himself emperor on 14 September 987.
Basil II turned to the Kievan Rus' for assistance, even though they were considered enemies at that time.
Vladimir agreed, in exchange for a marital tie; he also agreed to accept Christianity as his religion and to Christianize his people.
When the wedding arrangements were settled, Vladimir dispatched 6,000 troops to the Byzantine Empire, and they helped to put down the revolt.

In 988 and 991, he baptized Pecheneg princes Metiga and Kuchug, respectively.
