My vote goes to Aragon. I can't believe they aren't included. True, the were the secondary faction during the Reconquista, but they also heald many possessions on the Mediterranean such as Corsica, Sardinia and Sicily.
The Teutonic Knights would be fun to play, but they had no where near as much impact as the Aragonese.
Tribes? eh no, no no no no no. The were divided into three dominating factions who were vying for dominance. just a struggle to establish a strong central monarchy like was happening all over europe. In fact ireland would have been more centralised than the france at this stage.
