Placidia was the daughter of Roman Emperor Theodosius I and his second wife Galla. Her older

died with their mother. Placidia was a younger, paternal half-sister of Emperors Arcadius
and Honorius. Her older half-sister Pulcheria predeceased her parents as mentioned in the
writings of Gregory of Nyssa, placing the death of Pulcheria prior to the death of Aelia
Flaccilla, first wife of Theodosius I, in 385. Her paternal grandparents were Count
Theodosius and his wife Thermantia, as mentioned in the "Historia Romana" by Paul the Deacon.
Her maternal grandparents were Valentinian I and his second wife Justina, as mentioned by
Placidia, daughter of the preceding by Theodosius. When Alaric
took Rome in A.D. 410, she fell into his hands, and four years
later was married by Ataulphus, king of the Goths. Upon his
death she was returned to her country, and in 417 married
Constantius III., by whom she had the emperor Valentinian III.
During the minority of her son she was regent of the Western
Empire, dying about the year 450. See Gibbon, Decline and
