Reign of Heraclius

Heraclius seized the throne from Phocas and reigned for thirty years of extreme reversals. The Persians took Syria, Jerusalem and Egypt until his campaigns of 622–628 forced them to make peace; within a decade the Arabs overran the recovered provinces, and his attempt to reunite the church around the doctrine of one will failed.

Heraclius was the son of Heraclius the Elder, exarch of Africa, who rebelled against Phocas in 608. While his cousin Nicetas took Egypt, the younger Heraclius sailed for Constantinople; the palace guard went over to him, and on 5 October 610 he was crowned and Phocas executed. The empire he inherited was falling apart. After defeating Heraclius himself near Antioch in 613, the armies of Khosrow II took Syria, captured Jerusalem in 614, carrying off the relic of the True Cross, and by 621 held Egypt, which fed the capital; the Avars and Slavs pressed into the Balkans. By some accounts Heraclius thought in 618 of moving his court to Carthage, but Patriarch Sergius and the people dissuaded him, and church treasures were melted down to pay for a new army.

On 4 April 622 Heraclius left the capital and for six years led the war in person, striking through Armenia and the Caucasus into Persian territory. In 626, while he was away, Constantinople withstood a siege by the Avars acting in concert with a Persian army; an alliance with the Western Turks brought their forces into Transcaucasia, and late in 627 Heraclius defeated the Persians near Nineveh and advanced towards Ctesiphon. Khosrow II was overthrown and killed by his son Kavad II, who made peace, agreeing to give back the occupied provinces. In 629 or 630 Heraclius restored the True Cross to Jerusalem, and from 629 he officially styled himself basileus, a title his successors kept.

The triumph did not last. Arab armies defeated the Byzantines at the Yarmuk in 636, Syria and Palestine were lost within a few years, and by the time Heraclius died on 11 February 641 most of Egypt had fallen. His church policy failed too: to win back the Miaphysites of the recovered provinces, he and Sergius promoted the doctrine of a single energy in Christ and then, in the Ecthesis of 638, of a single will; Rome rejected it, and it was condemned at the Sixth Ecumenical Council in 680–681. Historians often date to his reign the final shift from Latin to Greek as the language of government, although no law on it is recorded; he was long credited with creating the military themes, but modern scholarship places them later.
