Ancient invaders (5)
(Other definitions for goths that I've seen before include "Germanic invaders of Roman empire" , "Rome's Germanic invaders" , "Tribesmen who brought down the Roman empire" , "A Teutonic people who invaded the Roman Empire" , "Ancient Germans who gave their name to a style of architecture" .)
'ancient invaders' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Another definition for huns that I've seen is " Attila's people".)
