are there any plausible PoD's for the island of Sardinia to remain, religiously, majority-muslim until at least the late modern age?
Why didn't the most powerful medieval muslim states like the Umayyads, Cordobans, Fatimids and possibly the sicilian Qalpids bother conquering the island? On a map, it looks as equally close to Africa as it is to Europe. I heard the Ottomans had plans to conquer it before their defeat at Lepanto.
