Heraclius (Latin: Flavius Heraclius Augustus, Greek: Φλάβιος Ἡράκλειος, c. 575 – February 11, 641) was Byzantine Emperor from 610 to 641.^{[A 1]}

He was responsible for introducing Greek as the Eastern Empire's official language. His rise to power began in 608, when he and his father, Heraclius the Elder, the exarch of Africa, successfully led a revolt against the unpopular usurper Phocas.

Heraclius' 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 ongoing war against the Sassanids. The first battles of the campaign ended in defeat for the Byzantines; the Persian army fought their way to the Bosphorus. However, because Constantinople was protected by impenetrable walls and a strong navy, 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 Khosrau II was assassinated soon after and peace was restored to the two deeply strained empires.

However, soon after his victory he faced a new threat, the Muslim invasions. Emerging from the Arabian Peninsula, the Muslims quickly conquered the collapsing Persian empire. In 634 the Muslims invaded Roman Syria, defeating Heraclius' brother Theodore. Within a short period of time the Arabs would also conquer Mesopotamia, Armenia, and Egypt.

In religious matters, Heraclius is remembered as the driving force in converting the peoples migrating to the Balkan Peninsula. At his request, Pope John IV (640–642) sent Christian teachers and missionaries to Dalmatia, a newly Croat-ruled province settled by Porga and his clan, who practiced Slavic paganism. 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.^[4] Eventually, however, this project of unity was rejected by all sides of the dispute. Heraclius was the first Emperor to engage the Muslims; in the Islamic tradition he is portrayed as an ideal ruler who corresponded with Muhammad, was a true believer of Islam, and viewed Muhammad as the true prophet, the messenger of God.^[5]

Early life[link]

Origins[link]

Heraclius was the eldest son of Heraclius the Elder and Epiphania, an Armenian family from Cappadocia.^{[A 2][6]} Beyond that, there is little specific information known about his ancestry. His father was a key general during Emperor Maurice's war with Bahrām Chobin, usurper of the Sassanid Empire, during 590.^[7] After the war, Maurice appointed Heraclius the Elder to the position of Exarch of Africa.^[7]

Revolt against Phocas and accession[link]

In 608, Heraclius the Elder renounced his loyalty to the Emperor Phocas, who had overthrown Maurice six years earlier. The rebels issued coins showing both Heraclii dressed as consuls, though neither of them explicitly claimed the imperial title at this time.^[8] Heraclius' younger cousin Nicetas launched an overland invasion of Egypt; by 609, he had defeated Phocas' general Bonosus and secured the province. Meanwhile, the younger Heraclius sailed eastward with another force via Sicily and Cyprus.^[8]

As he approached Constantinople, he made contact with prominent leaders and planned an attack to overthrow aristocrats in the city, and soon arranged a ceremony where he was crowned and acclaimed as Emperor. When he reached the capital, the Excubitors, an elite Imperial Guard unit led by Phocas' son-in-law Priscus, deserted to Heraclius, and he entered the city without serious resistance. When Heraclius captured Phocas, he asked him, "Is this how you have ruled, wretch?" Phocas said in reply, "And will you rule better?" With that, Heraclius became so enraged that he beheaded Phocas on the spot.^[9] He later had the genitalia removed from the body because Phocas had raped the wife of Photius, a powerful politician in the city.^[10]

On October 5, 610, Heraclius was crowned for a second time, this time in the Chapel of St. Stephen within the Great Palace, and at the same time married Fabia, who took the name Eudokia. After her death in 612, he married his niece Martina in 613; this second marriage was considered incestuous and was very unpopular.^[11] In the reign of Heraclius' two sons, the divisive Martina was to become the center of power and political intrigue. Despite widespread hatred for Martina in Constantinople, Heraclius took her on campaigns with him and refused attempts by Patriarch Sergius to prevent and later dissolve the marriage.^[11]

War against Persia[link]

To the brink of defeat[link]

During his Balkan Campaigns, Emperor Maurice and his family were murdered by Phocas in November 602 after a mutiny.^[12] Khosrau II (Chosroes) of the Sassanid Empire had been restored to his throne by Maurice and they had remained allies.^{[A 3]} Thus, the Persian King Khosrau II seized the pretext to attack the Byzantine Empire, and reconquer the Byzantine province of Mesopotamia.^[13] Khosrau had at his court a man who claimed to be Maurice's son Theodosius; and Khosrau demanded that the Byzantines accept this Theodosius as Emperor.

The war initially went the Persians' way, partly because of Phocas' 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.^[12] Phocas, an unpopular ruler who is invariably described in historical sources as a "tyrant", was eventually deposed by Heraclius, who sailed to Constantinople from Carthage with an icon affixed to the prow of his ship.^[14][15]

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.^[16] Over the following decade the Persians were able to conquer Palestine and Egypt (by mid-621 the whole province was in their hands^[17]) and to devastate Anatolia,^{[A 4]} 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 616.^[12]

With the Persians at the very gate of Constantinople, Heraclius thought of abandoning the city and moving the capital to Carthage, but was convinced to stay by the powerful church figure Patriarch Sergius. 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.^[19] 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.^[20]

Byzantine Empire strikes back[link]

On April 5, 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.^{[20][21][22][23]}

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.^[24] He would stay on campaign for several years.^[25][26] On March 25, 624 Heraclius left again Constantinople with his wife, Martina, and his two children; after he celebrated Easter in Nicomedia on April 15, he campaigned in the Caucasus, winning a series of victories in Armenia against Khosrau and his generals Shahrbaraz, Shahin and Shahraplakan.^[27][28] In 626 the Avars and Slavs besieged Constantinople, supported by a Persian army commanded by Shahrbaraz, 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^[29]), while a second Persian army under Shahin suffered another crushing defeat at the hands of Heraclius' brother Theodore.

With the Persian war effort disintegrating, Heraclius was able to bring the Gokturks of the Western Turkic Khaganate, Ziebel, who invaded Persian Transcaucasia. Heraclius exploited divisions within the Persian Empire, keeping the Persian general Shahrbaraz neutral by convincing him that Khosrau had grown jealous of him and 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.^[30] Continuing south along the Tigris he sacked Khosrau'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, Khosrau was overthrown and killed in a coup led by his son Kavadh II, who at once sued for peace, agreeing to withdraw from all occupied territories.^[31] In 629 Heraclius restored the True Cross to Jerusalem in a majestic ceremony.^[15][32][33]

Heraclius took for himself the ancient Persian title of "King of Kings" after his victory over Persia. Later on, starting in 629, he styled himself as Basileus, the Greek word for "sovereign", and that title was used by the Roman 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 having to do with Heraclius' Armenian origins.^[34]

Heraclius' defeat of the Persians had been the end game in a war that had been on and off for almost 800 years, when Alexander the Great had totally defeated the Persians. After Heraclius' victory over the Persian Empire left it in disarray which it never recovered. In 633 the new Islamic State slowly devoured the Persians until the Muslim conquest of Persia led to the end of the Sassanid Empire in 644, and the Sassanid dynasty in 651.^[35]

War against the Arabs[link]

The Islamic Prophet Muhammad had recently succeeded in unifying all the nomadic tribes of the Arabian Peninsula. The Arab tribes had been too divided in the past to pose a serious military threat to the Byzantines or the Persians. Now unified and animated by their new conversion to Islam, they comprised one of the most powerful states in the region.^[36] The first conflict between the Byzantines and Muslims was the Battle of Mu'tah in September 629. A small Muslim skirmishing force attacked the province of Arabia but were repulsed. Because the engagement was a Byzantine victory, there was no apparent reason to make changes to the military configuration of the region.^[37] Also, once the severity of the Muslim threat was realized, the Byzantines had little preceding battlefield experience with the Arabs, and even less with zealous soldiers united by a prophet.^[38] Even the Strategicon, a manual of war praised for the variety of enemies it covers, does not mention warfare against Arabs at any length.^[38]

The following year the Muslims launched raids into the Arabah south of Lake Tiberias, taking Al Karak. Other raids penetrated into the Negev reaching as far as Gaza.^[39] Islamic sources record that Heraclius dreamt of the coming Arab invasion. Historian Al-Tabari wrote that Heraclius dreamt of a new kingdom of the "circumcised man" that would be victorious against all its enemies.^[40] After telling his court his dream, his patricians, who did not know of the rise of Islam in Arabia, "advised him to send orders to behead every Jew in his dominion."^[40]

It was only when a Bedouin trader speaking of a man uniting the tribes of Arabia under a new religion was brought before the Emperor did Heraclius and his court realize that the kingdom of the "circumcised man" was not the Jews but the new Islamic Empire.^[40] When the Muslim Arabs attacked Syria and Palestine in 634, he was unable to oppose them personally in battle. Although he remained strategically in charge of operations, his generals failed him in battle. The Battle of Yarmouk in 636 resulted in a crushing defeat for the larger Byzantine army; within three years, the Levant had been lost again. By the time of Heraclius' death, on February 11, 641, most of Egypt had fallen as well.

Islamic view of the Emperor[link]

In Islamic and Arab histories Heraclius is the only Roman Emperor who is discussed at any length.^[41] Owing to his role as the Roman Emperor at the time Islam emerged, he was remembered in Arabic literature, such as the Islamic hadith and sira. Outside of Islamic sources there is no evidence to suggest Heraclius ever heard of Islam,^[42] and it is possible that he and his advisors actually viewed the Muslims as some special sect of Jews,^[38]

In Surah 30, the Qur'an refers to the Perso-Roman wars as follows:

30:2 Certainly, the Romans will be defeated. 3 In the nearest land. After their defeat, they will rise again and win. 4 Within several years. Such is GOD's decision, both in the first prophecy, and the second. On that day, the believers shall rejoice 5 in GOD's victory. He grants victory to whomever He wills. He is the Almighty, Most Merciful.^[43]

The Swahili "Utendi wa Tambuka", an epic poem composed in 1728 at Pate Island (off the shore of present-day Kenya) and depicting the wars between the Muslims and Byzantines from the former's point of view, is also known as Kyuo kya Hereḳali ("The book of Heraclius"). In that work, Heraclius is portrayed as declining the Prophet's command to renounce his false belief in Christianity; he is therefore defeated by the Muslim forces.^[44] This reflects the considerable impression which this Emperor made on his Muslim foes, being still prominently remembered by Muslims more than a millennium after his death and at a considerable geographical and cultural distance.

In Muslim tradition he is seen as a just ruler of great piety, who had direct contact with the emerging Islamic forces.^[45] The 14th-century scholar Ibn Kathir (d. 1373) went even further stating that "Heraclius was one of the wisest men and among the most resolute, shrewd, deep and opinionated of kings. He ruled the Romans with great leadership and splendor."^[41] Historians such as Nadia Maria El-Cheikh and Lawrence Conrad note that Islamic histories even go so far as claiming that Heraclius recognized Muhammad as the true prophet and proclaimed him the messenger of God.^[46][47][48]

Islamic historians often cite a letter that they claim Heraclius wrote to Muhammad "I have received your letter with your ambassador and I testify that you are the messenger of God found in our New Testament. Jesus, son of Mary, announced you."^[45] According to the Muslim sources reported by historian El-Cheikh, he tried to convert the ruling class of the Empire, but they resisted so strongly that he reversed his course and claimed that he was just testing their faith in Christianity.^[49] In El-Cheikh's interpretation, his status as a true believer in Islamic teaching should be seen as a way to legitimize Muhammad as the true prophet: if a foreign emperor, who is viewed as an almost perfect ruler, believes in Islam's message, then Muhammad must be the true prophet and voice of God.^[5] El-Cheikh notes that these accounts of Heraclius add "little to our historical knowledge" of the emperor, although they are an important part of "Islamic kerygma." ^[50]

Legacy[link]

Looking back at the reign of Heraclius, scholars have credited him with many accomplishments. He enlarged the Empire and his reorganization of the government and military were great successes. His attempts at religious harmony failed, but he succeeded in returning the True Cross, one of the holiest Christian relics, to Jerusalem.

Accomplishments[link]

Although the territorial gains produced by his defeat of the Persians were lost to the advance of the Muslims, Heraclius still ranks among the great Roman Emperors. His reforms of the government reduced the corruption which had taken hold in Phocas' reign, and he reorganized the military with great success. Ultimately, the reformed Imperial army halted the Muslims in Asia Minor and held on to Carthage for another 60 years, saving a core from which the empire's strength could be rebuilt.^[51]

The recovery of the eastern areas of the Roman Empire from the Persians once again raised the problem of religious unity centering around the understanding of the true nature of Christ. Most of the inhabitants of these provinces were Monophysites who rejected the Council of Chalcedon.^[52] Heraclius tried to promote a compromise doctrine called Monothelitism; however, this philosophy was rejected as heretical by both sides of the dispute. For this reason, Heraclius was viewed as a heretic and bad ruler by some later religious writers. After the Monophysite provinces were finally lost to the Muslims, Monotheletism rather lost its raison d'être and was eventually abandoned.^[52]

One of the most important legacies of Heraclius was changing the official language of the Empire from Latin to Greek in 620.^[53] The Croats and Serbs of Byzantine Dalmatia initiated diplomatic relations and dependencies with Heraclius.^[54] The Serbs, who briefly lived in Macedonia, became foederati, and were baptized at the request of Heraclius (before 626).^[54][55] At his request, Pope John IV (640–642) sent Christian teachers and missionaries to Duke Porga and his Croats, who practiced Slavic paganism.^[56] He also created the office of sakellarios, a comptroller of the treasury.^[57]

Up to the 20th century he was credited with establishing the Thematic system but modern scholarship now points more to the 660s, under Constans II.^[58]

The modern day border of Turkey can be attributed to Heraclius. This border was Heraclius' line of defence in Eastern Anatolia which would permanently define the border between lands Islamised by Arabs in the first flush of Islamic conquest and those which would only be Islamised many centuries later — by Turks.

Heraclius returns the True Cross to Jerusalem, anachronistically accompanied by Saint Helena. 15th century, Spain

Edward Gibbon in his work The History of the Decline and Fall of the Roman Empire wrote:

Of the characters conspicuous in history, that of Heraclius is one of the most extraordinary and inconsistent. In the first and last years of a long reign, the emperor appears to be the slave of sloth, of pleasure, or of superstition, the careless and impotent spectator of the public calamities. But the languid mists of the morning and evening are separated by the brightness of the meridian sun; the Arcadius of the palace arose the Caesar of the camp; and the honor of Rome and Heraclius was gloriously retrieved by the exploits and trophies of six adventurous campaigns. [...] Since the days of Scipio and Hannibal, no bolder enterprise has been attempted than that which Heraclius achieved for the deliverance of the empire.^[59]

Recovery of the True Cross[link]

Despite his actual Orthodox theology, Heraclius was long remembered favourably in the Western church for his reputed feat in recovering the True Cross, which had been captured by the Persians. As Heraclius approached the capital Khosrau fled from his favourite residence, Dastgerd (near Baghdad), without offering resistance. Meanwhile, some of the Persian grandees freed his eldest son Kavadh II, whom Khosrau II had imprisoned, and proclaimed him King on the night of 23–4 February, 628.^[60] Kavadh however was mortally ill and was anxious that Heraclius should protect his infant son Ardeshir. So, as a goodwill gesture, he sent the True Cross with a peace negotiator to sue for peace in 628.^[31]

After a tour of the Empire he returned the cross on March 21, 630.^[31][61] The story was included in the Golden Legend the famous 13th century compendium of hagiography, and he is sometimes shown in art, as in The History of the True Cross sequence of frescoes painted by Piero della Francesca in Arezzo, or a similar sequence on a small altarpiece by Adam Elsheimer (Städel, Frankfurt). Both of these show scenes of Heraclius and Constantine I's mother Saint Helena, traditionally responsible for the excavation of the cross. The scene usually shown is Heraclius carrying the cross; according to the Golden Legend he insisted on doing this as he entered Jerusalem, against the advice of the Patriarch. At first (shown above), when he was on horseback, the burden was too heavy, but after he dismounted and removed his crown it became miraculously light, and the barred city gate opened of its own accord.

Probably because he was one of the few Eastern Roman Emperors widely known in the West, the Late Antique Colossus of Barletta was considered to depict Heraclius.

Family[link]

Heraclius was married twice: first to Fabia Eudokia, a daughter of Rogatus, and then to his niece Martina. He had two children with Fabia and at least nine with Martina, most of whom were sickly children.^{[A 5][64]} Of Martina's children at least two were disabled, which was seen as punishment for the illegality of the marriage: Fabius (Flavius) had a paralyzed neck and Theodosios, who was a deaf-mute, married Nike, daughter of Persian general Shahrbaraz or daughter of Niketas, cousin of Heraclius.

Two of Heraclius' children would become Emperor: Martina's son Constantine Heraclius (Heraklonas), from 638 – 641, and Heraclius Constantine (Constantine III), his son from Eudokia, from February, 641 – May, 641.^[64]

Heraclius had at least one illegitimate son, John Athalarichos, who conspired a plot against Heraclius with his cousin, the magister Theodorus, and the Armenian noble David Saharuni.^{[A 6]} When Heraclius discovered the plot he had Atalarichos' nose and hands cut off and he was exiled to Prinkipo, one of the Princes' Islands.^[68] Theodorus had the same treatment but was sent to Gaudomelete (possibly modern day Gozo Island) with additional instructions to cut off one leg.^[68]

During the last years of Heraclius' life, it became evident that a struggle was taking place between Heraclius Constantine and Martina, who was trying to position her son Heraklonas in line for the throne. When Heraclius died, in his will he left the empire to both Heraclius Constantine and Heraklonas to rule jointly with Martina as Empress.^[64]
