feature of Arcadius's reign. The first crisis facing the young Arcadius was the rebellion of the Visigoths in 395, under the command of Alaric I (), who sought to take advantage of the accession of two inexperienced Roman emperors. As Alaric marched towards Constantinople, plundering Macedonia and Thrace, the eastern court could offer no response, as the majority of its army had gone to Italy with Theodosius and was now in the hands of Stilicho. Perhaps sensing an opportunity to exercise power in the eastern half of the empire as well, Stilicho declared that Theodosius had made him guardian over both his sons. He traveled eastward, ostensibly to face Alaric, leading both his own forces and the Gothic mercenaries whom Theodosius had taken west in the civil war with Eugenius. Arcadius and Rufinus felt more threatened by Stilicho than by Alaric; upon landing in Thessaly Stilicho received an imperial order to send along the eastern regiments, but himself to proceed no further. Stilicho complied, falling back to Salona while Gainas led the mercenaries to Constantinople. Arcadius and his entourage received Gainas in the Campus Martius, a parade ground adjacent to the city, on 27 November 395. There Rufinus was suddenly assassinated by the Goths, on the orders of Stilicho and possibly with the support of Eutropius. The murder certainly created an opportunity for Eutropius and for Arcadius' wife, Eudoxia, who took Rufinus' place as advisors and guardians of the emperor. While Eutropius consolidated his hold on power in the capital, the distracted government still failed to react to the presence of Alaric in Greece. At first Eutropius may have coordinated with Stilicho around the defence of Illyricum; by 397, when Stilicho personally led a blockade that compelled Alaric to retreat into Epirus, the atmosphere of the eastern court had changed. As neither Arcadius nor Eutropius was keen to have Stilicho intervening in the affairs of the eastern empire, they provided no further military aid to Stilicho, who then abandoned the blockade of the Visigoths. At Eutropius's urging, Arcadius declared Stilicho to be a hostis publicus, and came to an arrangement with Alaric, making him magister militum per Illyricum. At around the same time, the eastern court persuaded Gildo, the magister utriusque militiae per Africam, to transfer his allegiance from Honorius to Arcadius, causing relations between the two imperial courts to deteriorate further. Eutropius' influence lasted four years, during which time
