Sadat, possibly, supporting unlawful act in conflict (7,3)

I believe the answer is:
crimean war
'conflict' is the definition.
(1850s conflict)
'sadat possibly supporting unlawful act' is the wordplay.
I cannot quite understand how this works, but
'sadat' could be 'anwar' (I've seen this before) and 'anwar' is located in the answer.
'act' could be 'crime' (crime is a kind of act) and 'crime' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for crimean war that I've seen before include "Conflict in 1853-56" , "Hostilities" , "1850s conflict" , "conflict with Russia" .)
