Seen a few TLs, challenges and speculation on Al-Andalus over the past while and have been meaning to explore this.
Title basically sums up what I'm asking. Is there any way we could see Christianity or Islam- whichever ends up dominating Iberia, being more tolerant of the other.
I realize that in Al-Andalus, Christians were tolerated far more than Muslims were in the post-Reconquista. However, that doesn't mean there weren't persecutions and iirc the Christian population was dwindling. The northern christian kingdoms also remained largely hostile to the dynasties/taifas iirc, though obviously there's lots of shades of gray. Obviously, Jews and Muslims suffered a lot in the Reconquista and things did not work out so well for religious diversity after that. However, I've also read that some cities like Toledo actually harbored Muslims and Jews, so clearly it's not just one side's bad or one side's good.
What I wonder is, is it possible for Christians, Muslims and Jews to have less violence and discrimination amongst each other, enough to insulate communities in any future-state- which I assume will likely be either Christian or Muslim. That doesn't mean the absence of or even a comfortable level of tolerance, just simply more than we saw IOTL- enough so that we don't have something as wide-spread and destructive like the Inquisition (or if there "has" to be one perhaps one that left more religious diversity in the peninsula). What would it take to get this and how would it be done?
