Byzantine Empire under the Heraclian dynasty

The Byzantine Empire was ruled by emperors of the dynasty of Heraclius between 610 and 711 AD. The Heraclians presided over a period of foreign invasions like the last Byzantine-Sasanian War and the Muslim conquests, which marked a major changing point in the history of the Empire and the end of its hegemony in the continent. Heraclius, the founder of his dynasty, was of Armenian and Cappadocian (Greek) origin.
