I was thinking of doing a TL, but dont know whcih TL too do... I have some choices however going through my head.
Choice 1: Sancho, son Ferdinand of Leon-Castille dies as a child. Leon-Castile given too Alfonso after Ferdinand's death, and Galicia given too Garcia. Garcia remains independent from Leon-Castile.
This will follow Galicia as it continues on the struggles of independence.
Choice 2: Al-Andalus never pushes as much into Iberia, which stops the Reconquista?
This follows Al-Andalus as it becomes the major power in Iberia and a colonial power?
(I like the first one better...)
Feel free to add your own ideas for a first time TL writer.
