What Was the Long-Term Impact of the Crusades on Relations Between the Catholic and Orthodox Churches?

💡 The Answer

• The Fourth Crusade's sack of Constantinople in 1204 deepened the existing East-West Schism of 1054.
• Latin crusaders installed a Catholic patriarch in Constantinople, replacing the Orthodox hierarchy.
• Attempts at reunion, like the Second Council of Lyon in 1274, failed due to mutual suspicion.
• The bitterness over the Crusades contributed to the Orthodox rejection of Catholic authority to this day.
• These events cemented the division between Eastern and Western Christianity for centuries.
