The correct answer to this open question is the following.
The meaning of the religious destruction in Constantinople for Christians elsewhere in Europe must have been a devastating moment for the destruction of saints relics, churches.
The fall of Constantinople was the consequence of the victory of the Ottomans. Muslim Sultan Mehmed II conquered the capital of the Byzantine Empire in May 1453. Ottoman troops attacked Constantinople by sea and land, and after 55 days, Constantinople had fallen.
The implication of this defeat was that the Ottomans Muslims gain control over this important city and trade center than represented the heart of the Byzantine Empire and Christianity in Europe.
