Heraclius, with Heraclius Constantine. 610-641. Byzantine Silver Hexagram NGC VF.Heraclius(Greek: Ἡράκλειος, translit. Hērákleios; c. 575 – 11 February 641), was Eastern Roman emperor from 610 to 641. His rise to power began in 608, when he and his father, Heraclius the Elder, the exarch of Africa, led a revolt against the unpopular usurper Phocas. Heraclius's reign was marked by several military campaigns. The year Heraclius came to power, the empire was threatened on multiple frontiers. Heraclius immediately took charge of the Byzantine–Sasanian War of 602–628. The first battles of the campaign ended in defeat for the Byzantines; the Persian army fought their way to the Bosphorus but Constantinople was protected by impenetrable walls and a strong navy, and Heraclius was able to avoid total defeat. Soon after, he initiated reforms to rebuild and strengthen the military. Heraclius drove the Persians out of Asia Minor and pushed deep into their territory, defeating them decisively in 627 at the Battle of Nineveh. The Persian king Khosrow II was overthrown and executed by his son Kavad II, who soon sued for a peace treaty, agreeing to withdraw from all occupied territory. This way peaceful relations were restored to the two deeply strained empires.
However, Heraclius soon lost many of his newly regained lands to the Rashidun Caliphate. Emerging from the Arabian Peninsula, the Muslims quickly conquered the Sasanian Empire. In 636, the Muslims marched into Roman Syria, defeating Heraclius's brother Theodore. Within a short period of time, the Arabs conquered Mesopotamia, Armenia and Egypt. Heraclius responded with reforms which allowed his successors to combat the Arabs and avoid total destruction.
Heraclius entered diplomatic relations with the Croats and Serbs in the Balkans. He tried to repair the schism in the Christian church in regard to the Monophysites, by promoting a compromise doctrine called Monothelitism. The Church of the East (commonly called Nestorian) was also involved in the process.Eventually this project of unity was rejected by all sides of the dispute.Heraclius was the eldest son of Heraclius the Elder and Epiphania. His father, Heraclius the Elder, is almost universally recognized as being of Armenian origin. His mother, Epiphania, was probably of Cappadocian origin. Walter Kaegi considers Heracliusʼ Armenian origin "probable" and speculates that he was presumably "bilingual (Armenian and Greek) from an early age, but even this is uncertain." According to the 7th century Armenian historian Sebeos, Heraclius was related to the Arsacid dynasty of Armenia. Elizabeth Redgate considers his Armenian origin likely. However, Anthony Kaldellis argues that there is not a single primary source that says that Heraclius [the Elder] was an Armenian and that the assertion is based on an erroneous reading of Theophylact Simocatta. In a letter, Priscus, a general who had replaced Heraclius the Elder, wrote to him "to leave the army and return to his own city in Armenia". Kaldellis interprets it as the command headquarters of Heraclius the Elder, and not his home town.Nevertheless, beyond that, there is little specific information known about his origin. His father was a key general during Emperor Maurice's war with Bahram Chobin, usurper of the Sasanian Empire, during 590.After the war, Maurice appointed Heraclius the Elder to the position of Exarch of Africa.
During his Balkan campaigns, Emperor Maurice and his family were murdered by Phocas in November 602 after a mutiny.Khosrow II (Chosroes) of the Sasanian Empire had been restored to his throne by Maurice, and they had remained allies until the latter's death.Thereafter, Khosrow seized the opportunity to attack the Byzantine Empire and reconquer Mesopotamia.Khosrow had at his court a man who claimed to be Maurice's son Theodosius, and Khosrow demanded that the Byzantines accept this Theodosius as emperor.
The war initially went the Persians' way, partly because of Phocas's brutal repression and the succession crisis that ensued as the general Heraclius sent his nephew Nicetas to attack Egypt, enabling his son Heraclius the younger to claim the throne in 610. Phocas, an unpopular ruler who is invariably described in historical sources as a "tyrant" (in its original meaning of the word, i.e. illegitimate king by the rules of succession), was eventually deposed by Heraclius, who sailed to Constantinople from Carthage with an icon affixed to the prow of his ship.
By this time, the Persians had conquered Mesopotamia and the Caucasus, and in 611 they overran Syria and entered Anatolia. A major counter-attack led by Heraclius two years later was decisively defeated outside Antioch by Shahrbaraz and Shahin, and the Roman position collapsed; the Persians devastated parts of Asia Minor and captured Chalcedon across from Constantinople on the Bosporus.
Over the following decade the Persians were able to conquer Palestine and Egypt (by mid-621, the whole province was in their hands) and to devastate Anatolia,while the Avars and Slavs took advantage of the situation to overrun the Balkans, bringing the Empire to the brink of destruction. In 613, the Persian army took Damascus with the help of the Jews, seized Jerusalem in 614, damaging the Church of the Holy Sepulchre and capturing the True Cross, and afterwards capturing Egypt in 617 or 618.[25] When the Sasanians reached Chalcedon in 615, it was at this point, according to Sebeos, that Heraclius had agreed to stand down and was about ready to allow the Byzantine Empire to become a Persian client state, even permitting Khosrow II to choose the emperor.In a letter delivered by his ambassadors, Heraclius acknowledged the Persian empire as superior, described himself as Khosrow II's "obedient son, one who is eager to perform the services of your serenity in all things", and even called Khosrow II the "supreme emperor".Khosrow II nevertheless rejected the peace offer, and arrested Heraclius' ambassadors.
With the Persians at the very gate of Constantinople, Heraclius thought of abandoning the city and moving the capital to Carthage, but the powerful church figure Patriarch Sergius convinced him to stay. Safe behind the walls of Constantinople, Heraclius was able to sue for peace in exchange for an annual tribute of a thousand talents of gold, a thousand talents of silver, a thousand silk robes, a thousand horses, and a thousand virgins to the Persian King.The peace allowed him to rebuild the Empire's army by slashing non-military expenditure, devaluing the currency, and melting down, with the backing of Patriarch Sergius, Church treasures to raise the necessary funds to continue the war.
Byzantine counter-offensive and resurgence
On 4 April 622, Heraclius left Constantinople, entrusting the city to Sergius and general Bonus as regents of his son. He assembled his forces in Asia Minor, probably in Bithynia, and, after he revived their broken morale, he launched a new counter-offensive, which took on the character of a holy war; an acheiropoietos image of Christ was carried as a military standard.
The Roman army proceeded to Armenia, inflicted a defeat on an army led by a Persian-allied Arab chief, and then won a victory over the Persians under Shahrbaraz. Heraclius would stay on campaign for several years. On 25 March 624,he again left Constantinople with his wife, Martina, and his two children; after he celebrated Easter in Nicomedia on 15 April, he campaigned in the Caucasus, winning a series of victories in Armenia against Khosrow and his generals Shahrbaraz, Shahin, and Shahraplakan. In the same year the Visigoths succeeded in recapturing Cartagena, capital of the western Byzantine province of Spania, resulting in the loss of one of the few minor provinces that had been conquered by the armies of Justinian I. In 626 the Avars and Slavs supported by a Persian army commanded by Shahrbaraz, besieged Constantinople, but the siege ended in failure (the victory was attributed to the icons of the Virgin which were led in procession by Sergius about the walls of the city),while a second Persian army under Shahin suffered another crushing defeat at the hands of Heraclius's brother Theodore.
With the Persian war effort disintegrating, Heraclius was able to bring the Gokturks of the Western Turkic Khaganate, under Ziebel, who invaded Persian Transcaucasia. Heraclius exploited divisions within the Persian Empire, keeping Shahrbaraz neutral by convincing him that Khosrow had grown jealous of him and had ordered his execution. Late in 627 he launched a winter offensive into Mesopotamia, where, despite the desertion of his Turkish allies, he defeated the Persians under Rhahzadh at the Battle of Nineveh. Continuing south along the Tigris he sacked Khosrow's great palace at Dastagird and was only prevented from attacking Ctesiphon by the destruction of the bridges on the Nahrawan Canal. Discredited by this series of disasters, Khosrow was overthrown and killed in a coup led by his son Kavad II, who at once sued for peace, agreeing to withdraw from all occupied territories.In 629 Heraclius restored the True Cross to Jerusalem in a majestic ceremony.
Heraclius took for himself the ancient Persian title of "King of Kings" after his victory. Later on, starting in 629, he styled himself as Basileus, the Greek word for "sovereign", and that title was used by the Byzantine emperors for the next 800 years. The reason Heraclius chose this title over previous Roman terms such as Augustus has been attributed by some scholars to his Armenian origins.
Heraclius's defeat of the Persians ended a war that had been going on intermittently for almost 400 years and led to instability in the Persian Empire. Kavad II died only months after assuming the throne, plunging Persia into several years of dynastic turmoil and civil war. Ardashir III, Heraclius's ally Shahrbaraz, and Khosrow's daughters Boran and Azarmidokht all succeeded to the throne within months of each other. Only when Yazdgerd III, a grandson of Khosrow II, succeeded to the throne in 632 was there stability. But by then the Sasanid Empire was severely disorganised, having been weakened by years of war and civil strife over the succession to the throne. The war had been devastating, and left the Byzantines in a much-weakened state. Within a few years both empires were overwhelmed by the onslaught of the Arabs,ultimately leading to the Arab conquest of Persia and the fall of the Sasanian dynasty in 651.
