Galla Placidia
Theodosius had two sons and a daughter, Pulcheria, from his first wife, Aelia Flacilla. His daughter and wife had died in 385. By his second wife, Galla, the daughter of Valentinian the Great, he had a daughter, Galla Placidia; his son Gratian did not survive infancy. Galla Placidia, having grown up at Constantinople, married first Athaulf, king of the Visigoths, and then the future Constantius III. Both her husbands died not long after the marriages, and Constantius III, who succeeded Honorius as "augustus", reigned for less than a year. Galla Placidia and Constantius had two children: the future Valentinian III, who became "augustus" in the western empire, and Justa Grata Honoria.
