Arab and Muslim Slavery - an inconvenient truth - by Thomas Sowell

Blacks, Muslims and Arabs were the great slave traders of Blacks. Some 50 million were enslaved. Whites were also enslaved en masse by the Muslims - some 25 millions over 1400 years.

Black slaves were treated far worse by Muslims than Whites in general as given by death rates and the mere fact that no Black culture exists within Arab countries or the emirates to which Blacks were sent.

The great Christian David Livingstone provided first hand proof of the barbarity of the Arab-Black slave trade still thriving in the mid to late 19th century.  His journeys were undertaken to shine a light on this barbarism and end it. 

Today some 5 million Blacks are still enslaved by Blacks and Muslims.
