Constantine III
From LoveToKnow 1911
CONSTANTINE III., son of the emperor Heraclius (d. 641) by his first wife Eudocia, succeeded his father as joint-emperor with Heracleonas, the son of Heraclius by his second wife Martina. Court intrigues nearly led to a civil war, which was prevented by the death of Constantine (May 641), after a brief reign of 103 days. He was supposed to have been poisoned by order of his step-mother Martina.
