Monophysite Schism

Timeline

1. 451–500Chalcedon · AnatoliaThe Fourth Ecumenical Council at Chalcedon in 451 ruled that Christ has two natures, divine and human, provoking resistance from Monophysites in Egypt, Syria, and elsewhere. Sectarian conflict in the later 5th century had already sparked riots and episcopal turnover, laying the groundwork for the institutionalized schism of the 6th century.
2. 527–548Constantinople · Byzantine EmpireJustinian I attempted to bridge the rift with the Monophysites through measures such as the Three Chapters Edict, but met opposition from Pope Vigilius and the Western Church, instead intensifying East-West church tensions and leaving political and theological reconciliation in difficulty.
3. 501Egypt and Syria · EgyptThe Coptic Church, the Syrian Jacobites (Syrian Orthodox Church), and the Armenian Church formed independent non-Chalcedonian systems in the 6th century, remaining long separated from the orthodox churches of Constantinople and Rome, affecting Byzantine integration of Egypt and Syria and the later religious landscape after the Islamic conquests.
