The Peninsular Arabs, or Gulf Arabs, have the least outside influence, the Levantine Arabs were influenced by and mixed with the Greeks, Canaanites, and Bedouins of the Levant, and the North African Arabs were influenced by and mixed with the Berbers and in some cases the Copts though this was less common as the Copts preferred to pay the jizya
