What happened
Around 987, Byzantine Emperor Basil II asked Vladimir, ruler of Kievan Rus since he had defeated his brother Yaropolk I in a succession war, for military help against two rivals for his throne. Vladimir agreed and asked for or was offered Basil's sister Anna in marriage, a match the Byzantines approved only on condition that Vladimir convert to Christianity. The pact Christianized Kievan Rus and also created the Varangian Guard: Vladimir sent 6,000 Varangian warriors to Constantinople around 988, and they became the elite bodyguard of Byzantine emperors into the 14th century. A later, competing account claims Vladimir sent envoys to study Judaism, Islam, and Christianity before choosing Orthodoxy for the beauty of its Constantinople churches and its lack of a ban on alcohol or pork, a story that likely appeared a century later to make his conversion look like an independent choice rather than a marriage contract.
Why it matters
The choice of Orthodox Christianity in its Slavic-language form, rather than Latin Catholicism or Islam, set Rus culture on a different path from Catholic Europe for the next thousand years, including its later alphabet, art, and eventual claim to be the successor of Byzantium after Constantinople's fall in 1453.
How we know
The main narrative comes from the Russian Primary Chronicle, which preserves both the marriage-diplomacy account and the later legend of Vladimir's comparative religious survey; historians treat the marriage-and-alliance version as the more reliable core of the story.
