License produced peace (7)
I believe the answer is:
silence
'peace' is the definition.
(I've seen this before)
'license produced' is the wordplay.
'produced' indicates anagramming the letters.
'license' anagrammed gives 'SILENCE'.
(Other definitions for silence that I've seen before include "may be required in court" , "Quietness" , "Soundlessness" , "It is said to be golden" , "What's left of burnt coal" .)
