Byzantine Empire /
(401-450) Byzantine emperor 408-450.
Theodosius was, as his father, Arcadius, a weak ruler. He proved unable to exercise his influence, and much of the politics were in the hands of his relatives and ministers. His sister, Pulcheria, was of great influence, having herself crowned empress when he was 13 years old.
This period was one of many wars, with heavy military challenges on all fronts. Yet, the integrity of most of its borders was upheld. The empire was unable to defeat the Vandals in North Africa, defeated a Sassanid Persian invasion. The Huns under the leadership of Attila were the only ones successfully intruding on imperial territory, forcing the Byzantines to pay heavy tribute.
Fights over Christian doctrines continued during his reign. Thedosius appointed Nestorius Patriarch of Constantinople, which caused much anger among other Christian leaders. He would be removed after only 3 years.
Influenced by Pulcheria, Theodosius oversaw several actions against Jews, including the destruction of many synagogues.
