Constantine and Heroclonas

When Emperor Heraclius died on 11 February 641, he left two of his sons in charge. Each was from a different mother.

Constantine, his son by his first wife, Fabia Eudokia, had been crowned co-emperor on 22 January 613, when the child was only eight months old. This honorary title was a way to ensure succession in the event of the father's death, but did not give him the emperor's authority while his father lived. (The illustration shows a gold solidus with father and son displayed.)

Heraclonas, his son by Martina, had been made a caesar (a royal title but not the same as emperor) at the age of six years, on 1 January 632. On that same day, Constantine was given a consulship, which made him one of the highest-ranking men in the empire with actual authority. Heroclonas was named "Augustus" and essentially a co-emperor on 4 July 638.

Heraclius' favoring of Martina, who naturally tried to promote her own children over that of her step-son, led to a weakening of Constantine's roles.

At Heraclius' death, however, Constantine became senior emperor. Constantine promoted his own son, Constans (who was only 11 years old) to caesar, ignoring Martina's other sons. Because Heraclonas was so young, Martina made decisions on his behalf, often arguing with Constantine.

Some of Constantine's supporters feared that Martina and Heraclonas would try to overthrow him, and advised him to make sure the army was loyal. Constantine sent two million solidi to Valentinus, to ensure that the army would support Constans.

Constantine died within a few months of becoming emperor. The cause is assumed to be tuberculosis, although rumors that he was poisoned by Martina persisted. That's when the money sent to Valentinus came in handy, as I'll explain tomorrow.
