What happened
In 1652, Tsar Alexis appointed the forceful and popular priest Nikon as Patriarch of Moscow. Nikon had come to believe, partly through contact with visiting Greek clergy such as Patriarch Paisius of Jerusalem, that Russian liturgical practice had drifted from Greek Orthodox practice through centuries of copying errors, and that correcting it would strengthen pan-Orthodox unity. Starting in Great Lent 1653, he ordered changes including the sign of the cross be made with three fingers instead of the traditional two, and that sixteen full prostrations during a key Lenten prayer be reduced to four. Traditionalist clergy led by Archpriest Avvakum rejected the changes, noting the two-fingered cross had been explicitly endorsed by the Stoglav Council of 1551. The Great Moscow Synod of 1666-1667 sided with Nikon's reforms, condemned Avvakum and the traditionalists, and formally created the Old Believer movement as a separate, persecuted community outside the official church.
Why it matters
The schism split Russian Orthodoxy for the remainder of imperial Russian history; Old Believer communities faced persecution for centuries, some responding with mass self-immolation in apocalyptic despair, while others fled to remote regions of the empire and even abroad, and Old Believer communities survive today.
How we know
Church council records from the 1666-1667 Great Moscow Synod, along with Avvakum's own surviving autobiography written from exile, document both sides of the dispute in detail.
