Theodosius II

Theodosius II, nicknamed the Calligrapher, who lived from 10 April 401 to 28 July 450, served as Roman emperor of the eastern empire from 402 to 450, proclaimed Augustus as an infant and becoming sole ruler on his father Arcadius's death in 408. His reign produced the Theodosian law code, the Theodosian walls that protected Constantinople, and the founding in 425 of what is described as the oldest university in the world, the University of Constantinople; he also presided over the Nestorian and Eutychian controversies over the nature of Christ. He married Aelia Eudocia in June 421, with whom he had at least two daughters, Licinia Eudoxia and Flaccilla, and possibly a son named Arcadius. He died on 28 July 450 from a horse riding accident; his successor Marcian came to power after Theodosius's sister Pulcheria married him on 25 November 450.
