This man's father was exe
This man's father was executed after putting down Firmus's rebellion against Romanus. Early in this man's rule, his general, Modares, had a number of victories in the Balkans. This leader had Demophilus expelled from Constantinople. Along with his much younger colleague, he fought a civil war against the usurper Magnus Maximus and later this man won the battle of the Frigidus against the usurping Arbogast and Eugenius. This man was made emperor by his temporary colleague, Gratian. He was succeeded by his children Arcadius and Honorius. St. Ambrose excommunicated this emperor over a massacre in Thessalonica and this man had earlier called the First Council of Constantinople. He effectively outlawed paganism in the empire. For 10 points, name this last Emperor to rule both the Eastern and Western Roman Empires, who died in 395 CE.
