Tiberius Julius Alexander (fl. 1st century) was an equestrian governor and general in the Roman Empire. Born into a wealthy Jewish family of Alexandria but abandoning or neglecting the Jewish religion, he rose to become procurator of Judea (c. 46–48) under Claudius. While Prefect of Egypt (66–69), he employed his legions against the Alexandrian Jews in a brutal response to ethnic violence, and was instrumental in the Emperor Vespasian's rise to power. In 70, he participated in the Siege of Jerusalem as Titus' second-in-command.
Tiberius Julius Alexander was probably born early in the reign of the Emperor Tiberius (14–37). His father was Alexander, an Alexandrian Jew who held the office of Alabarch; the exact meaning of this term is debated, but it may have denoted a senior customs official. The older Alexander enjoyed Roman citizenship, a rare privilege among the Jews of Alexandria, and therefore passed it to his sons. He also had business connections both with Agrippa, grandson of Herod the Great, and with Antonia, mother of the emperor Claudius. Another prominent member of Tiberius Alexander's family was his uncle, the philosopher Philo.
Tiberius' younger brother Marcus Julius Alexander would follow their father into business, becoming a partner in an import-export firm. Marcus Julius Alexander was the first husband of Herodian Princess Berenice. Marcus died in 43 or 44, leaving no children. Tiberius himself decided differently, setting out upon a military and administrative career in the service of the Roman Empire. When introducing Tiberius, the Jewish historian Josephus condemns him for his impiety and explains that he "did not remain in his ancestral customs". This has traditionally been taken to mean that he became an apostate from Judaism at an early age, a view which finds some support in his appearance as a character in two of Philo's philosophical dialogues, making arguments against divine providence which Philo attempts to refute. However, some more recent scholars believe that Josephus is criticizing Alexander simply for his decision to take up the service of Rome, placing the interests of the Empire above the Jewish religion.
He nevertheless continued to benefit from his family's connections, which were enhanced after the Emperor Claudius came to power in 41. Agrippa had helped to secure Claudius' accession after the assassination of Caligula, and was appointed king of Judea. Tiberius' father, who had been imprisoned by Caligula, was released on Claudius' orders, and his younger brother Marcus became first husband to Agrippa's daughter Berenice.
Career until 63
Despite the disadvantages posed by his Alexandrian and Jewish origin, Tiberius Alexander was evidently well enough connected for an equestrian career in Roman public life. The first position he is known to have held, beginning in about 42, was that of epistrategus of the Thebaid, one of the three regions into which the Roman province of Egypt was divided. This was an administrative and judicial post involving no military command. He could have maintained contact with his brother Marcus, who was trading in the same area until his premature death in 43 or 44.
A promotion came in c. 46, when Alexander was appointed procurator of Judea by Claudius. The province had returned to direct Roman rule only after the death of Agrippa in 44, and the tenure of Alexander's predecessor Cuspius Fadus had been marked by unrest, so Alexander's Jewish background may have marked him as a more acceptable governor. Less trouble is attested during his office, although he did condemn James and Simon, sons of an earlier rebel named Judas of Galilee, to crucifixion. It was also at this time that Judea was afflicted by a severe famine. In 48 he was succeeded by Ventidius Cumanus.
Alexander's subsequent activities are unknown until the reign of Nero, when he served as a staff officer under the prominent general Gnaeus Domitius Corbulo during campaigns against Parthia. In 63 he was dispatched along with Corbulo's son-in-law to escort the Armenian king Tiridates to the Roman camp, on the first stage of his journey to receive the status of client king from Nero.
Prefecture of Egypt
In May 66, Nero appointed Alexander as Prefect of Egypt, one of the two most prestigious posts available to an equestrian along with Prefect of the Praetorian Guard. Alexander may have benefitted from a philhellenic tendency in equestrian appointments under Nero, but his experience of Egypt must also have commended him. However, any hope that he would be able to quell the recurring conflicts in his province between Greek and Jewish populations proved to be short-lived. The year he assumed office saw the outbreak of the First Jewish–Roman War in Judea, and aggression inevitably spilled over into the large Jewish community of Alexandria. An outbreak of ethnic violence during a Greek assembly escalated when the Greeks took prisoners, leading the Jewish side to threaten to burn the assembled Greeks to death. Alexander sent mediators to calm the Jews, warning he would have to use the Roman legions if violence continued. The threat was ineffective, and Josephus describes the outcome:
A less violent side to Alexander's government is demonstrated by other evidence. Over a century after his time, his administrative decisions were still being cited as precedents. Some of these are known from a surviving edict issued on July 6, 68, less than a month after Nero's death. This denounces, and introduces measures against, a variety of abuses including inaccurate tax assessments, malicious prosecutions and the imprisonment of debtors by private creditors. The edict's only allusion to the chaotic political situation comes as a call for trust in the benevolence of the new Emperor, Galba, and his ability to put right the wrongs of the past. Alexander was making representations to Galba on behalf of the provincials, presumably representing the desired reforms as the price of loyalty from this vital grain-producing province.
Neither Galba nor his successor Otho survived long in office. In April 69, Vitellius was recognized as Emperor by the Roman Senate, but his opponents were beginning to rally behind Vespasian, commander of the Roman forces conducting the war in Judea. The loyalties of Alexander, who commanded two legions and had control of the grain shipments from Alexandria to Rome, were of crucial importance. Fortunately for Vespasian, Alexander was willing to correspond with him secretly; go-betweens suspected by modern historians include Berenice (soon to be lover of Vespasian's son Titus), and an Egyptian official named Basilides. On July 1 Alexander became the first to make a decisive move against Vitellius: on receipt of a letter from Vespasian, he instructed his forces to take the oath of allegiance to Vespasian as Emperor. His lead was followed by legions throughout the eastern Empire, and the anniversary of Vespasian's accession was later celebrated on this date.
Siege of Jerusalem
Vespasian moved rapidly to Egypt, leaving the Jewish war under the command of Titus. At the same time Alexander, as a proven commander with experience of Jewish affairs, was sent by Vespasian to join Titus as his chief of staff and adviser, second only to Titus himself. By April 70, Jerusalem was under siege by four legions, and even after the city walls were overcome, the defenders held out in the Temple. Alexander, the offspring of a pious Jewish family, whose own father had donated the gold and silver for the Temple gates, now found himself in a position of command against his former brothers in that very sanctuary.
Despairing of any siege operation against the Temple's massive walls, Titus had the gates burnt down. At the ensuing council of war, when it was debated whether to destroy the entire Temple, Alexander voted with the majority who favored preservation. In the event, this made no difference; as the fighting raged on the following day, a Roman soldier hurled a burning brand into a chamber of the Temple itself. The Temple was consumed by the flames.
By this time, Vespasian's position in Rome was secure. The details of Alexander's career under the new emperor remain unclear. A damaged papyrus refers to Alexander as holding the position of "Praetorian Prefect", which is open to two interpretations. It could indicate his rank during Titus' campaign in 70, which would mean that he held his own independent imperium (commanding authority). According to another view, it means that he became Prefect of the Praetorian Guard at Rome, which in later years became a common position for former Prefects of Egypt. In either case, Alexander attained a position in the Roman Empire that was unparalleled for a man of Jewish birth, not to mention one who suffered from the further stigma of an Egyptian origin. The xenophobic speaker of Juvenal's first Satire, composed in the late 1st or early in the 2nd century AD, complains of passing the Forum's triumphal statues, "where some Egyptian Arabarch's had the nerve to set up his titles. At his image it's right to do more than piss!" This is very likely a reference to Alexander.
