Tiberius Julius Alexander orders his Roman legions in Alexandria to swear allegiance to Vespasian as Emperor.

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 the 2nd 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. He became the most powerful Jew of his age, and is ranked as one of the most prominent Jews in military history.
