Remember, people, that we should always keep in mind all three scenarios. In this case, specially the third one.
If so... well, think of this map, the 1300 line:
(The map is not very good... for example Toledo is awfully north, but since it was not Spanish-made, I preferred to use it)
It makes no sense that, let's say, the count of Sevilla or the count of Cordoba not to have the same in-game mechanisms that the Count of Tolouse or the Count of Montpellier have in regard to France (and they were acquired by those crowns in not too far apart dates).
This should be the minimum the initial christian kingdoms setup in Iberia should cover. If you notice, the territory covered by the Kingdom of Granada is only four provinces: Granada, Almeria, Malaga and (EDIT)Algeciras. Question is... are we going to create a fantasy kingdom for
four provinces? Would the king of Castilla and Leon not have all the right of the world in the Hundred War scenario not to get incredibly pissed if another christian power would come to conquer what is in all regards a client kingdom which he does not squash because he prefers to just get the money of the taxes, thank you?
EDIT: Finally it was Cadiz, not Algeciras... I was thinking of Cadiz, since it is now part of the Cadiz province.
