君士坦斯二世
Constans was the son of Constantine III and Gregoria. After the death of Constantine III's father Heraclius, Constantine ruled with his half-brother Heraklonas through Heraclius' second marriage to Martina. Due to rumors that Heraklonas and Martina poisoned Constantine III, Constans II was named co-emperor. Later that same year, his uncle was deposed by the general Valentinus, one of Heraclius’ most trusted generals, and Constans II was left as sole emperor.
