Winning the Campaign

[Rhyfelwyr]

I've completed a Short Campaign as Venice, and chose to play on. There's now one turn left, and I own every province but two. One is owned by Rebels, the other the Papal States. So, presuming there is a total domination victory video (even though I only had set to short campaign, does that matter?), do I only need to destroy the Rebels to win, leaving the Papal States with a province? Or do I need to conquer the Papal States region (Magdeburg) to gain total domination?

EDIT: Having just loaded up the campaign, I've noticed another issue. Because I killed the Pope and a new one was elected, I was reconciled. This meant I've lost all my siege equipment at Magdeburg, and will need to wait another turn to rebuild the ladders etc. This will mean I won't defeat the Papacy within the 226 turns. If I need to wait another turn and beat the on turn 227, do I still get to see a victory video for total domination?
