The history of the Jews in Alexandria dates back to the founding of the city by Alexander the Great in 332 BCE. Jews in Alexandria played a crucial role in the political, economic, cultural and religious life of Hellenistic and Roman Alexandria, with Jews comprising about 35% of the city's population during the Roman era.
In the Ptolemaic period, Alexandrian Jews played a central role in the development of Hellenistic Judaism and were instrumental in the translation of the Torah from Hebrew to Koine Greek, which produced the Septuagint. Many important Jewish writers and figures came from or studied in Alexandria, such as Philo, Ben Sira, Tiberius Julius Alexander and Josephus. The position of Alexandria's Jewry began deteriorating during the Roman era, as deep antisemitic sentiment began developing amongst the city's Greek and Egyptian populations. This led to the subsequent Alexandrian pogrom in 38 CE and the Alexandria riot in 66 CE, which was in parallel with the outbreak of the First Jewish–Roman War. Alexandria's Jewry began to diminish, leading to a mass immigration of Alexandrian Jews to Rome, as well as other Mediterranean and North African cities. It appears that the Jewish community of Alexandria was completely eradicated by the end of the Diaspora Revolt in 117 CE, with various rabbinic legends associated with the final destruction of the community.
