Basic Pod, the Byzantines are able to keep the Islamic conquests out of the Maghreb. So what would be the impact on Western Europe ?
Unlike with keeping the Muslim out of Spain only, in this case there would be a lack of raids from North Africa. So I would imagine maritime trade and coastal settlements are going to be more secure. Likewise I imagine a lot more trade between North Africa and Europe with additional European access to Sub-Saharan African goods. I assume without the religious divide, conquests either from Africa into Europe or vice versa is going to be easier.
