Theodosius was born in 401, became Augustus the next year, and sole Augustus in the East in 408 when his father, the Emperor Arcadius, died.
He was influenced heavily by his sister Pulcheria and banned pagans from holding office. Hypatia was murdered in Alexandria at this time.
Two councils were held at Ephesus, one to set an opinion on the Nestorian theological position and a second, known as the Robber Council in which the position was taken that there was one nature of Christ (monophysite). This was the beginning of the break between the Church in the East and West.
Theodosius gave away Roman lands to the Vandals and went from paying an annual 350 pounds of gold to the Huns to 2100.
In February 438, Theodosius II published a collection of the Roman laws known as the Codex Theodosianus.
Theodosius died of a riding accident in 450.
