Alexandria translated the Old Testament into Greek. This translation is called the Septuagint. The translation of the Septuagint itself began in the 3rd century BCE and was completed by 132 BCE, initially in Alexandria, but in time elsewhere as well. It became the source for the Old Latin, Slavonic, Syriac, Old Armenian, Old Georgian, and Coptic versions of the Christian Old Testament. The Jewish community of Alexandria was "extinguished" by Trajan's army during the Kitos War of 115–117 CE, also known as the Diaspora Revolt. The Jewish revolt, which is said to have begun in Cyrene and spread to Egypt, was largely motivated by religious zealotry, aggravation after the failed Great Revolt and destruction of the Temple, and anger at discriminatory laws. Byzantine or Eastern Roman Empire The greatest blow Alexandrian Jews received was during the Byzantine Empire rule and the rise of a new state religion: Christianity. There was an expulsion of a large amount of Jews from Alexandria (the so-called "Alexandria Expulsion") in 414 or 415 CE by Saint Cyril, following a number of controversies, including threats from Cyril and supposedly (according to Christian historian Socrates Scholasticus) a Jewish-led massacre in response. Later violence took on a decidedly anti-Semitic context with calls for ethnic cleansing. Before that time, state/religious-sanctioned claims of a Jewish pariah were not common. In The History of the Decline and Fall of the Roman Empire, Edward Gibbon describes the Alexandria pogrom: Without any legal sentence, without any royal mandate, the patriarch (Saint Cyril), at the dawn of day, led a seditious multitude to the attack of the synagogues. Unarmed and unprepared, the Jews were incapable of resistance; their houses of prayer were leveled with the ground, and the episcopal warrior, after rewarding his troops with the plunder of their goods, expelled from the city the remnant of the unbelieving nation. Some authors estimate that around 100 thousand Jews were expelled from the city. The expulsion then continued in the nearby regions of Egypt and Palestine followed by a forced Christianization of the Jews. Arab rule (641 to 1250) The Arab conquest of Egypt at first found support from Jewish residents as well, disgruntled by the corrupt administration of the Patriarch Cyrus of Alexandria, notorious for his Monotheletic proselytizing. In addition to the Jewish population settled there from ancient times, some are said to have come from the Arabian Peninsula. The letter sent by Muhammad
