so according to your logic the moors had impact in south america because south spain was under arabs for a little while?
it has not any sense
when south italy was under spain (1300s-1700s) it was among the most powerful countries in the world and it had no any moors impact at that time
spaniards had the most impact in south italy, culture, behaviour etc... tons of local words come from spain and according to a ndrangheta legend the three major mafias were formed by three spanish riders in 1300s
