As in the title, how can an earlier Reconquista happen and what are its effect on the general history of the region and Mediterranean as a whole?
I've heard there was a "fitna" in Cordoba during the 9th century but I was unable to find much information about it, at least looking through easily accessible stuff, but if that's the case and the disorded escalates further, can it lead to an earlier Reconquista phase before the Asturian kingdom breaks up?
