Description

Heraclius (Latin: Flavius Heraclius Augustus, Greek: Φλάβιος Ἡράκλειος) was the Emperor of the Byzantine Empire from 610 to 641.

He was responsible for introducing Greek as the Eastern Roman Empire's official language. 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 was sole ruler until 22 January 613, when he crowned his son Constantine III as co-emperor.

Towards the end of his reign, Heraclius also named his young son Constantine Heraclius (commonly known by the diminutive Heraklonas) as Augustus on 4 July 638.

On Heraclius's death on 11 February 641, Constantine III and Constantine Heraclius were proclaimed joint emperors.
