Just as the racist imaginary of Europeans about Black Africans has centered since the 18th century on the term “monkey/ape”, that of Arabs has centered, since at least the middle ages, on the term “ʿabd” (“slave”). According to this imaginary, any black person is, by definition, a slave. As such, this book discusses anti-Black racism in Mecca and in other Arab regions, as well as the ancient presence of the Black diaspora in Mecca and Hijaz and the contribution it has made in different areas. The book also looks at the teaching system in the al-Haram Mosque of Mecca, its religious and political role, and the way it was dispensed during the Ottoman period, the reign of Sharīf Husayn and the political regime of the Āl Sa'ūd Wahhābī.
