The challenge is to make the north African countries of Morocco, Algeria, Tunisia, Libya (and possibly Egypt) majority Christian by 1950 (this is in the pre-1900 forum because the PODs will most likely be before 1900). PODs after 1500 and before 1950. Here are some of the ideas I had:
Morocco: have Spain controlling and colonising Morocco and converting locals almost treating it like a Re-reconquista.
Algeria and Tunisia: French colonisation and conversion, similar to OTL just on a larger scale.
Libya: Italian colonisation similar to OTL
Egypt: Egypt is hard because of its large population but maybe a very early Coptic insurgency and Coptic control or something, I'm not too sure with this one.
