Is Russian Orthodoxy the Main Religion in Russia?

Yes, Russian Orthodoxy is the dominant religion in Russia, both demographically and culturally. Approximately 75% of the population identifies as Russian Orthodox Christians, making the Russian Orthodox Church (ROC) the country's largest religious organization with over 100 million nominal adherents.

Historical Roots

Christianity arrived in Kievan Rus' in 988 AD under Prince Vladimir. The ROC became autocephalous (self-governing) in 1448 and a patriarchate in 1589. Despite Soviet-era persecution (1917–1991), the church survived and regained immense influence post-1991.

Current Landscape

• Other Christians: Protestants, Catholics, Old Believers (~2–3%).
• Islam: Second-largest religion (~10–15%), concentrated in North Caucasus, Tatarstan, Bashkortostan, and Moscow.
• Other Faiths: Buddhism (Kalmykia, Buryatia), Judaism, Hinduism, others (~1%).
• Unaffiliated: ~15–20% identify as atheist, agnostic, or "spiritual but not religious."

Church-State Relations

The ROC enjoys a privileged position: chaplains in the military, religious education in public schools (optional), and close ties to the Kremlin. The 2020 constitutional amendments mention "faith in God" and protect "historical truth," further aligning church and state narratives.

While Russia is constitutionally secular, Russian Orthodoxy functions as a de facto national religion, shaping identity, politics, and public life.
