Violence ratings:
Not only is there no violence, there is no conflict of any kind.
Not so much as a fist fight.
A fight or two, definitely some kind of conflict, but no blood or guts.
Swordfights and other bloody scenes fairly common, but not described in detail.
Plenty of fighting, realistic and detailed descriptions of at least some of it.
Gore-o-rama, blood everywhere. You probably won't see any of these on this site.
