Black African and Near Eastern peoples have interacted since prehistoric times. Some historians estimate that as many as 14 million black slaves crossed the Red Sea, Indian Ocean, and Sahara Desert in the Arab slave trade from 650 to 1900 CE. The Moroccan Sultan Moulay Ismail "the Bloodthirsty" (1672–1727) raised a corps of 150,000 black slaves, called his Black Guard, who coerced the country into submission.
The Afro-Asiatic languages, which include Semitic languages such as Arabic and Hebrew, are believed by some scholars to have originated in Ethiopia. This is because the region has very diverse language groups in close geographic proximity, often considered a telltale sign for a linguistic geographic origin.
In more recent times, about 1000 CE, interactions between black people and Arabs resulted in the incorporation of extensive Arabic vocabulary into Swahili, which became a useful lingua franca for merchants. Some of this linguistic exchange occurred as part of the slave trade; the history of Islam and slavery shows that the major juristic schools traditionally accepted the institution of slavery. As a result, Arab influence spread along the east coast of Africa and to some extent into the interior (East Africa). Timbuktu was a trading outpost that linked west Africa with Berber, Arab, and Jewish traders throughout the Arab World. As a result of these interactions many Arab people in the Middle East have black ancestry and many black people on the east coast of Africa and along the Sahara have Arab ancestry.
According to Dr. Carlos Moore, resident scholar at Brazil's University of the state of Bahia, Afro-multiracials in the Arab world self-identify in ways that resemble Latin America. He claims that black-looking Arabs, much like black-looking Latin Americans, consider themselves white because they have some distant white ancestry.
