Answer
Claudius Gothicus ascended to the throne in 268 AD, succeeding Gallienus as the emperor of the Roman Empire. His reign was marked by decisive military victories against the invading Germanic tribes and the Goths, earning him the title "Gothicus" and restoring stability to the empire's frontiers. However, his rule was short-lived as he succumbed to the plague during a campaign against the Visigoths in 270 AD.
