Heraclius, Emperor of the East from 610 to 642, born in Cappadocia; raised to the throne of the East on account of the services he rendered the citizens of Constantinople in getting rid of a tyrant; waged war against the hostile Persians, defeated Chosroës, and compelled a peace, but was unable to withstand the arms of the Moslem invaders.
