[Sidenote: Constans II., 641-68.] Constantinus IV., or as he was more usually but less accurately styled Constans II.,[37] thus became the sole ruler of the East ere he had finished his twelfth year. The real government was, for some time, carried on by the senate—a fact which vouches both for the loyalty of the empire to the house of Heraclius and for the great rise in the power of the senate during the last two or three generations. In earlier days there is no doubt that some powerful general would have seized the throne. But Constantinus, though his minority was not untroubled by revolts, was permitted to grow up to man’s estate, and to assume in due course the personal control of the empire. Footnote 37: There is no doubt that his real name was Constantinus, or in full Flavius Heraclius Constantinus. But the Western historians, and some of those of the East, call him Constans. Probably this was a mere convenience to distinguish him from his father, Heraclius Constantinus, and his son, Constantine IV. (or V.).
