Ruled when conditions were bad, say (7)
I believe the answer is:
reigned
'ruled' is the definition.
('reign' can be a synonym of 'rule')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for reigned that I've seen before include "Maintained high position" , "Ruled" , "Held sway" , "Was king" , "Was monarch" .)
