Palmyrene Empire

Background

Following the murder of Roman emperor Alexander Severus in 235, general after general squabbled over control of the empire, the frontiers were neglected and subjected to frequent raids by Carpians, Goths and Alamanni, in addition to outright attacks from the aggressive Sassanids in the east. Finally, Shapur I of Persia inflicted a disastrous defeat upon the Romans at the Battle of Edessa in 260, capturing the Roman emperor Valerian and soon, Quietus and Macrianus rebelled against Valerian's son Gallienus and usurped the imperial power in Syria.

The Palmyrene leader Odaenathus was declared king, and remained nominally loyal to Gallienus, forming an army of Palmyrenes and Syrian peasants to attack Shapur. In 260, Odaenathus won a decisive victory over Shapur in a battle near the Euphrates. Next, Odaenathus defeated the usurpers in 261, and spent the remainder of his reign fighting the Persians. Odaenathus received the title Governor of the East, and ruled Syria as the imperial representative, and declared himself King of Kings. Odaenathus was assassinated along with his son Hairan in 267, and according to the Augustan History and Joannes Zonaras, Odaenathus was killed by his cousin whose name in the Augustan History is Maeonius. The Augustan History also claim that Maeonius was proclaimed emperor for a very brief period, before being executed by the soldiers. However, no inscriptions or other evidence exist for Maeonius' reign, and he was probably killed immediately after assassinating Odaenathus.

Odaenathus was succeeded by his minor sons with Zenobia; the ten-year-old Vaballathus. Under the regency of Zenobia, Vaballathus was kept in the shadow while his mother assumed actual rule and consolidated her power. The queen was careful not to provoke Rome and took for herself and her son the titles that her husband had, while working on guaranteeing the safety of the borders with Persia, and pacifying the dangerous Tanukhids tribes in Hauran.

Establishment

Aided by her generals, Septimius Zabbai, a general of the army, and Septimius Zabdas, the chief general of the army, Zenobia started an expedition against the Tanukhids in the spring of 270, during the reign of emperor Claudius II. Zabdas sacked Bosra, killed the Roman governor and marched south securing Roman Arabia. According to the Persian geographer Ibn Khordadbeh, Zenobia herself attacked Dumat Al-Jandal but could not conquer its castle. However, Ibn Khordadbeh is confusing Zenobia with al-Zabbā, a semi-legendary Arab queen whose story is often confused with Zenobia's story.

In October of 270, a Palmyrene army of 70,000 invaded Egypt, and declared Zenobia queen of Egypt. The Roman general Tenagino Probus was able to regain Alexandria in November, but was defeated and escaped to the fortress of Babylon, where he was besieged and killed by Zabdas, who continued his march south and secured Egypt. Afterward, in 271, Zabbai started the operations in Asia Minor, and was joined by Zabdas in the spring of that year. The Palmyrenes subdued Galatia, and occupied Ankara, marking the greatest extent of the Palmyrene expansion. However, the attempts to conquer Chalcedon were unsuccessful.

The Palmyrene conquests were done under the protective show of subordination to Rome, Zenobia issued the coinage in the name of Claudius' successor Aurelian with Vaballathus depicted as king, while the emperor allowed the Palmyrene coinage and conferred the Palmyrene royal titles. However, toward the end of 271, Vaballathus took the title of Augustus (emperor) along with his mother.

Reconquest by Rome

In 272, Aurelian crossed the Bosphorus and advanced quickly through Anatolia. According to one account, Marcus Aurelius Probus regained Egypt from Palmyra, while the emperor continued his march and reached Tyana. The fall of Tyana lent itself to a legend; Aurelian to that point had destroyed every city that resisted him, but he spared Tyana after having a vision of the great philosopher Apollonius of Tyana, whom he respected greatly, in a dream. Apollonius implored him, stating: "Aurelian, if you desire to rule, abstain from the blood of the innocent! Aurelian, if you will conquer, be merciful!". Whatever the reason for his clemency, Aurelian sparing of Tyana paid off, many more cities submitted to him upon seeing that the emperor would not exact revenge upon them.

Entering Issus and heading to Antioch, Aurelian defeated Zenobia in the Battle of Immae. Zenobia retreated to Antioch then fled to Emesa while Aurelian advanced and took the former. After regrouping, the Romans first destroyed a Palmyrene garrison stationed at the fort of Daphne, and headed south to Apamea, then continued to Emesa and defeated Zenobia again at the Battle of Emesa, forcing her to evacuate to the capital. Aurelian marched through the desert and was harassed by Bedouins loyal to Palmyra; however, as soon as he arrived at the city gates, he negotiated with the Bedouins, who betrayed Palmyra and supplied the Roman army with water and food. Aurelian besieged Palmyra in the summer of 272, and tried to negotiate with Zenobia, on the condition that she surrender herself in person to him, to which she answered with refusal. The Romans tried to breach the city defenses several times but were repelled, however, as the situation deteriorated, Zenobia left the city and headed east to ask the Persians for help. The Romans followed the empress, arrested her near the Euphrates and brought her back to the emperor. Soon after, the Palmyrene citizens asked for peace, and the city capitulated.

Aftermath

Aurelian spared the city and stationed a garrison of 600 archers led by a certain Sandarion, as a peacekeeping force. The defenses were destroyed and most of the military equipments were confiscated. Zenobia and her council were taken to Emesa and put on trial. Most of the high ranking Palmyrene officials were executed, while Zenobia's and Vaballathus's fates are uncertain.

In 273, Palmyra rebelled under the leadership of a citizen named Septimius Apsaios, and contacted the Roman prefect of Mesopotamia Marcellinus offering him to usurp the imperial power. Marcellinus delayed the negotiations and sent word to the Roman emperor, while the rebels lost their patience and declared a relative of Zenobia named Antiochus as Augustus. Aurelian marched against Palmyra and was helped by a Palmyrene faction from inside the city, headed by a man with a senatorial rank named Septimius Haddudan.

Aurelian spared Antiochus, but razed Palmyra to the ground. The most valuable monuments were taken by the emperor to decorate his Temple of Sol, while buildings were smashed, people were clubbed and cudgeled and Palmyra's holiest temple pillaged.

Evaluation and legacy

The ultimate motive behind the revolt is debated; when dealing with the rise of Palmyra and the rebellion of Zenobia, historians most often interpreted the ascendancy as an indication of a cultural, ethnic or social factors. Andreas Alföldi viewed the rebellion as a completely native ethnic opposition against Rome. Irfan Shahîd considered Zenobia's revolt a pan-Arab movement that was a forerunner of the Arab expansion of the Caliphates; an opinion shared by Franz Altheim, and an almost universal view amongst Arab and Syrian scholars such as Philip Khuri Hitti. Mark Whittow refused that the revolt was ethnic in its nature and emphasized that it was a reaction to the weakness of Rome and its inability to protect Palmyra from the Persians. Warwick Ball viewed the rebellion as aimed at Rome's throne, not just Palmyrene independence. Vaballathus' inscriptions indicated the style of a Roman emperor; according to Ball, Zenobia and Vaballathus were contenders for the Roman imperial throne, following a plan similar to that of Vespasian, who ascended the throne after building his power-base in Syria. Andrew M. Smith II considered the revolt as a bid for both independence and the Roman throne. The Palmyrene royalty used Eastern titles such as king of kings, which had no relevance in Roman politics, while the conquests were in the interest of Palmyrene commerce. Finally, it was only in the last regnal year of Zenobia and Vaballathus that the Roman imperial rank was claimed. Fergus Millar, although tending toward the view that it wasn't only an independence movement, believes there is not yet enough evidence to conclude the nature of Palmyra's revolt.

The revolt of Palmyra is used as a theme in Syrian nationalism and Palmyra is viewed as exclusively Syrian, and treated as a fighting city that threw off the imperial dominance and relieved the people from tyranny. A Syrian TV show was produced based on Zenobia's life, and she was the subject of a biography written by Syria's former minister of defense Mustafa Tlass.
