Battle of Nineveh (627)

The Battle of Nineveh (Ἡ μάχη τῆς Νινευί) was the climactic battle of the Byzantine-Sassanid War of 602–628. The Byzantine victory later resulted in civil war in Persia and for a period of time restored the empire to its ancient boundaries in the Middle East. This resurgence of power and prestige was not to last, however, as within a matter of decades an Arab Caliphate emerged from Arabia and once again brought the empire to the brink of destruction.
