Theodosius II, son of Arcadius, became a "junior" Augustus for the East as a baby in 402, then "senior" Augustus at age 7 after his father's death in 408. His 15-year-old sister, Pulcheria, proclaimed herself regent over her brother, then thirteen years of age, and made herself Augusta and Empress of the Eastern Roman Empire. Even after Theodosius II came of age, she exerted a strong influence. He died of a riding accident in 450. Photo courtesy of Classical Numismatic Group, Inc.
