Herakleios (Latin: Heraclius; c. 575-641) was Byzantine Emperor from 610 to 641. He came to power after successfully leading a revolt against Phokas, the unpopular incumbent (who'd himself come to power just eight years prior through a revolt).

Herakleios' reign was marked by multiple conflicts with the empire's neighbors, which engendered reforms to the military and an expansion and reorganization of the empire. He also attempted to resolve the Monophysite issue by promoting a doctrine called Monothelitism (which was ultimately rejected). The dynasty he founded, the Heraclian Dynasty, continued until the death of Justinian II in 711.

Herakleios also made Greek the official language of the empire.

Herakleios in Justinian[]

In his memoir, Justinian II referred to Herakleios as "the great" on more than one occasion. He also looked to Herakleios for inspiration.

Justinian's uncle and brother were named for the great emperor.

Herakleios in Agent of Byzantium[]

In the years following Saint Mouamet's departure from Syria to the heart of the Roman Empire, Herakleios overthrew and supplanted the Emperor Phokas, and established a dynasty which included the great Constans II.[1]
