Ive always had a soft spot for the Normans, and norman Sicily in particular. One of the more interesting chapters in Sicilys history is the twenty odd year dominion over Tunis and Libya, the so called Norman Kingdom of Africa. In OTL these dominions were destroyed by the Almohads, who also definitvely ended the remnants of native Christianity in the process. My question is if this can be prevented, and Sicily maintains control over Roman Africa- does this lead to Tunis being culturally and religiously integrated with Sicily? Does it even open up further reconquests of the Maghreb? I assume that this will strengthen Sicily itself, as Africa was the granary of ancient Rome and could strengthen Sicily economy to day nothing of trade.
