Heraclius (Greek: Ἡράκλειος, translit. Hērákleios; c. 575 – 11 February 641), sometimes called Heraclius I, was the Eastern Roman emperor from 610 to 641. His rise to power began in 608, when he and his father, Heraclius the Elder, the exarch of Africa, led a revolt against the unpopular usurper Phocas. Heraclius's reign was marked by several military campaigns.
