Magnus Maximus
Following the defeat of Magnus Maximus by Theodosius in 388, Valentinian was restored to the throne. On 18 June 389, Theodosius arrived in Rome to display his second son, the five year old Honorius. He reconciled with Magnus Maximus' supporters and pardoned Symmachus, then in hiding, since he needed the support of the Gallo-Hispanic aristocracy, of which both he and Maximus were members. Theodosius then decided to stay in Milan, making sure that Valentinian was under the influence of his supporters. Overall, Theodosius, a skilled diplomat, made it clear that in practice he was the sole emperor of the two empires.
