Heraclius
Heraclius ("Flavios Iraklios"; c. 575 – February 11, 641) was the Emperor of the Byzantine Empire 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.
The year Heraclius came to power, the empire was threatened on multiple frontiers.
Heraclius immediately took charge of the Byzantine–Sasanian War of 602–628.
The first battles of the campaign ended in defeat for the Byzantines; the Persian army fought their way to the Bosphorus but Constantinople was protected by impenetrable walls and a strong navy, and Heraclius was able to avoid total defeat.
Soon after, he initiated reforms to rebuild and strengthen the military.
Heraclius drove the Persians out of Asia Minor and pushed deep into their territory, defeating them decisively in 627 at the Battle of Nineveh.
The Persian king Khosrow II was overthrown and executed by his son Kavad II, who soon sued for a peace treaty, agreeing to withdraw from all occupied territory.
This way peaceful relations were restored to the two deeply strained empires.
Heraclius lost many of his newly-regained lands to the Muslim conquests.
Emerging from the Arabian Peninsula, the Muslims quickly conquered the Sasanian Empire.
In 634 the Muslims marched into Roman Syria, defeating Heraclius's brother Theodore.
Within a short period of time, the Arabs conquered Mesopotamia, Armenia and Egypt.
Heraclius entered diplomatic relations with the Croats and Serbs in the Balkans.
He tried to repair the schism in the Christian church in regard to the Monophysites, by promoting a compromise doctrine called Monothelitism.
The Church of the East (commonly called Nestorian) was also involved in the process.
Eventually this project of unity was rejected by all sides of the dispute.

Heraklonas
Constantine Heraclius (Latin: "Flavius Constantinus Heraclius (Heraclianus)"; 626–641), commonly known by the diminutive Heraklonas or Herakleonas , or rarely, Heraclius II, was the son of Heraclius and his niece Martina.
His father had stipulated in his will that both of his sons should rule jointly upon his death.
Heraclius also specified that his wife, Martina, was to be called "Mother and Empress" insofar as she might have influence at court as well.
The emperor Heraclius died in February 641 from edema.
When Martina did make the late Emperor's will public
she faced staunch resistance to her playing any active role in government, but both Heraklonas and Constantine III were proclaimed joint-emperors in February 641 without incident.
After Constantine died of tuberculosis in April/May 641, Heraklonas became sole emperor, under the regency of his mother due to his young age.
He reigned from April/May – September/October 641, when he was overthrown by Valentinus, a general and usurper of Armenian extract, who installed Constans II, the son of Constantine III.
Valentinus had Heraklonas' nose cut off, then exiled him to Rhodes, where he is believed to have died in the same year.
