Writers born during different crises (7)
I believe the answer is:
scribes
'writers' is the definition.
(scribe is a kind of writer)
'born during different crises' is the wordplay.
'born' becomes 'b' (common abbreviation).
'during' indicates putting letters inside.
'different' indicates anagramming the letters.
'crises' with letters rearranged gives 'scries'.
'b' put into 'scries' is 'SCRIBES'.
(Other definitions for scribes that I've seen before include "People who once made hand-written copies" , "Copyists" , "journos" , "Ancient writers (7)" .)
