Byzantine–Sasanian War of 572–591

The Byzantine–Sasanian War of 572–591 was a war fought between the Sasanian Empire of Persia and the Byzantine Empire. It was triggered by pro-Byzantine revolts in areas of the Caucasus under Persian hegemony, although other events also contributed to its outbreak. The fighting was largely confined to the southern Caucasus and Mesopotamia, although it also extended into eastern Anatolia, Syria, and northern Iran.
