When the westerners came in they didn't know the terrain instead of the made allies with the Arabs and will wait at the coast and buy slaves from the Arabs.
The Africans who converted to Islam mostly by force like the ones you see in the video started helping their Arab masters to catch those Africans that were not Muslims, you know Islam calls for the enslavement of non-Muslims, one famous African who really took millions of Africans(non-Muslims) and sold to the Arab slave master is Tipo Tipp of Zanzibar. It's sad that so many African Americans don't know this if they knew none of them will be Muslim. I believe even Malcolm X didn't know this.
Both the Arab Semite, Jew Semite and European man all were terrible to black slaves. The Arab treatment was harsher and lasted longer but that does not absolve the European man from his role either. The white man in recent years has been working overtime to make European slavery of African blacks not seem so bad and confusing the issue with Irish indentured labor to make it seem as though white Irish had it harder than blacks. Although blacks were under Chattel slavery and were slaves for life and slaves for genetic reasons. While the white Irish were the only bond for a period of fewer than 10 years and their children were not enslaved.
From Islamic literature, manifestations of racism and racist discrimination subsequently followed within the Islamic world. For example, an Arab poet in the 7th century wrote: "The blacks do not earn their pay by good deeds, and are not of good repute; The children of a stinking Nubian black—God put no light in their complexions!"
Ethnic prejudices developed among Arabs for at least two reasons: 1) their extensive conquests and slave trade; and 2) the influence of Aristotle's idea of final causes which argues that slaves are slaves by nature.[POV? ] A refinement of Aristotle's view was put forward by Muslim philosophers such as Al-Farabi and Avicenna, particularly in regards to Turkic and black peoples; and the influence of ideas from the early mediaeval Geonic academies regarding divisions among mankind between the three sons of Noah.
However, ethnic prejudice among some elite Arabs was not limited to darker-skinned people, but was also directed towards fairer-skinned "ruddy people" (including Persians, Turks and Europeans), while Arabs referred to themselves as "swarthy people". The concept of an Arab identity itself did not exist until modern times. According to Arnold J. Toynbee: "The extinction of race consciousness as between Muslims is one of the outstanding achievements of Islam and in the contemporary world there is, as it happens, a crying need for the propagation of this Islamic virtue."
By the 14th century, an overwhelming number of slaves came from sub-Saharan Africa, leading to prejudice against black people in the works of several Arabic historians and geographers. For example, the Egyptian historian Al-Abshibi (1388–1446) wrote: "It is said that when the [black] slave is sated, he fornicates, when he is hungry, he steals."
Ibn Battuta who visited the ancient kingdom of Mali in the mid-14th century recounts that the local inhabitants vie with each other in the number of slaves and servants they have, and was himself given a slave boy as a "hospitality gift."
According to one professor, the view that Arab scholars and geographers from this time period held racist attitudes are the result of mistranslations, stating that such attitudes were not prevalent until the 18th and 19th century
