The people of the Maghreb and the Sahara speak various dialects of Berber and Arabic and almost exclusively follow Islam. The Arabic and Berber groups of languages are distantly related, both being members of the Afro-Asiatic family. The Sahara dialects are notably more conservative than those of coastal cities (see Tuareg languages). Over the years,Berber peoples have been influenced by other cultures with which they came in contact: Nubians, Greeks, Phoenicians, Egyptians, Romans, Vandals, Arabs, and lately Europeans. The cultures of the Maghreb and the Sahara therefore combine indigenous Berber, Arab and elements from neighboring parts of Africa and beyond. In the Sahara, the distinction between sedentary oasis inhabitants and nomadic Bedouin and Tuareg is particularly marked.
