Answer
The Battle of Naissus, fought in 268 AD near the modern-day city of Niš in Serbia, marked a significant victory for the Roman Empire against the invading Goths. Under the leadership of Emperor Claudius II, the Roman forces decisively defeated a vast Gothic army, halting their advance and securing the empire's frontiers. This triumph earned Claudius the honorific title "Gothicus Maximus" and solidified Rome's control over the Balkans.
