What was the Greek fire and why was it important?

Greek fire was a highly flammable liquid weapon developed by the Byzantine Empire, used primarily in naval warfare. Its exact composition remains a mystery, but it could ignite upon contact with water, making it particularly devastating in sea battles. Greek fire played a crucial role in the defense of Constantinople, helping to repel numerous sieges and maintain Byzantine power for centuries. Its effectiveness and the secrecy surrounding its production contributed to its importance in military history.
