Triumphs

I am playing the Romans and am trying to get a Triumph.

The character won imperator fighting rebels on auto-calc and I am now having him kill a lot of Dacians...is that an acceptable way to do this? (I mean does the imperator have to be linked to his campaign against a faction?)

Thanks.

Imperator is separate from the conquerer traits and you can get a triumph the way you are doing it.
