The residents of Bakh'a and Jubb'adin converted to Islam in the eighteenth century, while in Ma'loula, the majority are Christians, mainly belonging to the Melkite Greek Catholic Church, but also to the Greek Orthodox Church of Antioch, in addition to a Muslim minority, who speaks the same Aramaic dialect of the Christian residents.

By the Mameluke era, the Arabization of the Egyptian populace alongside a shift in the majority religion going from Christianity to Islam, had taken place. North Africa and Iberia Neither North Africa nor the Iberian Peninsula were strangers to Semitic culture: the Phoenicians and later the Carthaginians dominated parts of the North African and Iberian shores for more than eight centuries until they were suppressed by the Romans and by the following Vandal and Visigothic invasions, and the Berber incursions.
