Civil, religious, and military policies

After being installed as Emperor, Eugenius changed the imperial administrators. When Theodosius had left the western half of the empire to Valentinian II, he had put his own men in the highest civil offices, to keep a strong grasp on the whole empire. Eugenius replaced these administrators with others loyal to himself, coming from the senatorial class.

Fall

After his election as emperor, Eugenius sent two embassies to Theodosius's court, asking for recognition of his election. Theodosius received them, but both embassies were given vague responses and returned without completing their missions. In January 393, Theodosius promoted his eight-year-old son Honorius to the rank of ''
