![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
wars
'major conflicts' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for wars that I've seen before include "Armed conflicts against enemies" , "Battles" , "- - of the Roses" , "See 8" .)
