Constantine IV

Definition

Constantine IV ruled as emperor of the Byzantine empire from 668 to 685 CE. His reign is best remembered today for the five-year Arab siege of Constantinople from 674 CE, which the Byzantines resisted thanks to their strong fortifications and the secret weapon of Greek Fire. Although not hugely successful in other theatres, the reign of Constantine would at least stabilize the Empire, perpetuate the rule of Christianity in the East, and permit something of a revival of Byzantine fortunes under subsequent emperors.
