Europeans from Sedan (5)
I believe the answer is:
danes
'europeans' is the definition.
(Danish people)
'from sedan' is the wordplay.
'from' indicates an anagram (from the letters).
'sedan' anagrammed gives 'DANES'.
(Other definitions for danes that I've seen before include "E.g. Hamlet and Canute" , "people in Copenhagen" , "Scandinavians" , "Vikings" , "More than one member of kingdom" .)
