Theodosius of Alexandria
?–566 CE · Alexandria
Theodosius I served as the thirty-third Patriarch of Alexandria (535–566) and became the defining theological voice of Miaphysite Christianity after the Council of Chalcedon (451) had split Eastern Christendom. Elected amid violent rivalry with the Julianist counter-claimant Gaianus, he was summoned to Constantinople by Emperor Justinian I in 536 and spent the remaining thirty years of his patriarchate under imperial detention — governing the Coptic and broader Miaphysite world through correspondence rather than from his see. After the death of Severus of Antioch (538), Theodosius emerged as the undisputed head of non-Chalcedonian Christianity across the Byzantine Empire; from his place of detention he personally consecrated James Baradaeus as bishop of Edessa (c. 543/544), an act that reconstituted the Syriac Jacobite church. Under Justin II (who acceded 565), Theodosius was offered permission to return to Alexandria but died before he could depart, and was buried at Constantinople with patriarchal honours. His theological writings — a dogmatic Tome to Empress Theodora, polemics against Tritheism and Agnoetism, and a rich body of letters — articulate the Severan Miaphysite Christology that the Coptic Orthodox Church has maintained to the present day.

What they did here
Elected patriarch in 535 amid a violent popular uprising backing the rival Julianist claimant Gaianus; imperial troops restored Theodosius, but Justinian summoned him to Constantinople the following year.
Alexandria in this era
Reorganized within Diocletian's restructured empire after 284 CE, Alexandria became a foremost center of Christian theology and bitter doctrinal conflict, seat of a powerful patriarchate. It retained brilliant pagan learning into late antiquity—the Neoplatonist and mathematician Hypatia taught here until her murder by a Christian mob in 415 CE—before the city passed out of Roman hands with the Arab conquest of Egypt in 641 CE.
About Alexandria
Alexandria is the main Mediterranean port of northern Egypt and the country's second city. Founded by Alexander the Great in 331 BCE, it became the capital of the Ptolemies, whose Museum and Great Library made it the leading centre of Hellenistic learning. It also held one of the largest Jewish communities of antiquity, where the Greek Bible translation known as the Septuagint was produced and Philo wrote. Church tradition traces its patriarchate to Mark the Evangelist, and its catechetical school was led by Clement and Origen. Arab forces under Amr ibn al-As took the city in 641, and it remained a commercial and scholarly hub of the Islamic world; the Sufi master Ibn Ata Allah al-Iskandari was born there.
