12th-century illustration of the use of Greek fire

The first Arab siege of Constantinople in 674–678 was a major conflict of the Arab–Byzantine wars, and the first culmination of the Umayyad Caliphate's expansionist strategy towards the Byzantine Empire. In 672–673 Arab fleets secured bases along the coasts of Asia Minor, and set up a loose blockade around Constantinople. They used the peninsula of Cyzicus near the city as a base to spend the winter, and returned every spring to launch attacks against the city's fortifications. Finally the Byzantines managed to destroy the Arab navy using a new invention, the liquid incendiary substance known as Greek fire (pictured). The Byzantines also defeated the Arab land army in Asia Minor, forcing them to lift the siege. A peace treaty was signed, and following the outbreak of another Muslim civil war, the Byzantines experienced a brief period of ascendancy. The siege was the first major Arab defeat in 50 years of expansion. Tales of a large-scale siege of Constantinople even reached China. (Full article...)
