ガッラ・プラキディア
The two surviving sons of Theodosius ruled the eastern and western halves of the empire after their father died. Theodosius's second child by Galla, the daughter of Valentinian the Great by his second wife Justina, was Galla Placidia, born in 392 or 393. Galla Placidia's brother Gratian, the son of Galla and Theodosius, died in 394. Another son, John (), may have been born in 394. Galla Placidia married Athaulf, the King of the Visigoths in 414; he soon died and she married the "patricius" Constantius (later Constantius III) in 417. Their children were Justa Grata Honoria and Valentinian III. Constantius III was elevated to "augustus" in 421 by Honorius, who had no issue, and Galla Placidia was made "augusta"; Constantius died the same year and Galla Placidia fled to Constantinople.
