The Thervingi were possibly among the Goths who invaded the Roman Empire in the year 268. This invasion overran the Roman provinces of Pannonia and Illyricum and even threatened Italia itself. However, the Goths were defeated in battle that summer near the modern Italian-Slovenian border and then routed in the Battle of Naissus that September. Over the next three years they were driven back over the Danube River in a series of campaigns by the emperors Claudius II Gothicus and Aurelian.
