So don't create Hispania or unite the thrones and then your primary title is Leon or Castile which are pretty homogenous to begin with.
I started as Navarra and ran as Basque, so I had some cultural work cut out for me aside from the warfare.
The de jure drift right towards the end really screwed me as the duchy that drifted had a bunch of non-Basque counties in them. And the vassals who'd ruled the area for me for 50 years hadn't bothered to convert them to Basque.
I mean, the good news was that I had run with High Partition for 99% of the game. So, if I had been paying more attention, I could have created Leon or another smaller kingdom and destroyed Navarra. That would have canceled de jure drift to Navarra while I converted the counties.
Listen to me complaining about having
more de jure land in my realm.
I assumed you just wanted to get any ending
The Detente ending would be fine as it allows the creation of Hispania. Not ideal (I was going for Dominance), but I could still claim the proper empire.
Status quo would be problematic for me in this particular scenario for a whole list of reasons, including making the entire last 50 years pointless in terms of conquest. It would be like starting over
and letting other people form kingdoms and empires. (Not enough male dynasty members left alive at the moment to create a bunch of dynasts as kings.)
And I guess if you gave independence to the fresh conquered lands before they become de jure of your kingdom, Andalusia would snack them again, right?
Yep. That's why I kept up the pressure instead of doing something like stealing just a couple of counties. Andalusia formed a holy order right around the same time I formed the Hospitallers. Some of our big wars involved 20k per side in the 900s between mercenaries, holy orders hired for free, and allies.
Don't get me wrong: the AI gave me a decent game right up until the point where I reduced Andalusia to two counties in a massive war and I realized I wouldn't be able to fire the Domiannce ending before I could convert the new de jure counties. Plenty of intrigue, lots of screwing each other via diplomacy, and the staple of most CK3 games: people dying at inconvinent times so that successions go bad and alliances end right when you need them. Hell, Andalusia managed to do something I've never seen it do in Iberia: the Umayyads stayed in power
and remained powerful right up until I drove a stake through the heart of their empire. Usually, I see the YUMads collapse to religious rebels, dissolution wars, or bad successions. In this game, aside from a brief period when they split in half, they remained potent and strong throughout.
Maybe that's why I'm salty. It was a great game... right up until I achieved my major foreign policy goal, and I realized that everything I had fought for over the past century was meaningless because I can't reap the rewards for Dominance despite, well, being dominant. My "dominance" of Iberia failed because I mistimed some culture converting and de jure drift.
