When Galla married Theodosius, she became both a Roman empress and a stepmother to Theodosius’ two sons from his first marriage,
Arcadius and
Honorius. In July and August of 388, the combined troops of Theodosius I and Valentinian II invaded the territory of Maximus under the leadership of
Richomeres,
Arbogast,
Promotus, and
Timasius. Maximus suffered a series of losses and surrendered in
Aquileia. He was executed on 28 August 388 along with his son and nominal co-ruler
Victor, although the rest of his family were spared. Justina's condition for the marriage had been met, however she died the same year, unable to witness the result of her efforts. Theodosius spent the years 388–391 in Italia, while Galla and her stepsons remained in the
Great Palace of Constantinople. According to
Marcellinus Comes, Arcadius expelled her from the palace in 390. However, since Arcadius was only thirteen, that decision could as well have belonged to those who governed in his name. When Theodosius decided to return to the East, possibly due to the conflict between Galla and Arcadius, he installed Valentinian and his court at
Vienne in Gaul, away from Milan and the influence of
Ambrose, and appointed Arbogast as
magister militum for the Western provinces. On May 15, 392, Valentinian was discovered hanged in his room. His death was officially reported as a suicide, but
Arbogast was suspected to have had a hand in it, an accusation found in the writings of
Socrates of Constantinople,
Orosius, and
Zosimus.
Sozomen was less certain and mentioned both versions of how Valentinian II died. Galla did not live to see the victory. She died in childbirth, before the battle had started. == Issue ==
