Modern Portugal traces its roots to the successful independence war waged by Afonso I, who broke free from the Kingdom of Leon in 1129. But I wonder, how could Afonso I lose this war, and what would come of it? I imagine Portugal would be in a tense situation since the Leonese themselves were a problem for Castile, similar to the Welsh in England or the Italians in the HRE (but less rich).
But, how would the Iberian peninsula evolve? Would the Reconquista finish faster TTL? if so, do they muck around with North Africa like Portugal did, or would they be pulled in other directions? What about overseas exploration? Would it still be the 'Portuguese,' who kickstarted it (albeit on a smaller scale?) What does this mean for England, since they no longer have one of their first major alliances?
