“Yes, Alexandria Was a Major Christian Center Before the Muslim Conquest
Alexandria, Egypt, was one of the most prominent hubs of early Christianity for nearly six centuries, from its founding in the 1st century AD until the Arab Muslim conquest in 641 AD. It served as the seat of the Patriarchate of Alexandria—one of the five original “pentarchy” sees of the early Christian world (alongside Rome, Constantinople, Antioch, and Jerusalem)—and exerted profound theological, scholarly, and missionary influence across the Mediterranean and Africa. By the 7th century, Egypt (including Alexandria) was predominantly Christian, with the faith deeply embedded in urban and rural life, despite internal doctrinal disputes and Byzantine persecutions.”
Damned colonialist settler genocidal totalitarian foreigner ARABs should go back to ARABIA from which they launched their wars of conquest and leave ALEXANDRIA to its indigenous CHRISTIANS!!!

“Yes, there was a prolonged era when Alexandria was simultaneously under Christian political rule (i.e., governed by Christian Roman/Byzantine emperors and their appointees) and remained a major center of Jewish scholarship and culture—specifically from the early 4th century AD through the early 5th century AD, with lingering influence into the 6th century.”
