Trans-Saharan trade requires travel across the Sahara between sub-Saharan Africa and North Africa. While existing from prehistoric times, the peak of trade extended from the 8th century until the early 17th century. ... Cattle were introduced to the Central Sahara (Ahaggar) from 4000 to 3500 BC.
In his text "Slavery, a System of Inherent Cruelty," Theodore D. Weld shows how cattle were sometimes treated better than slaves. An example he gives of this is how cattle are allowed to graze as much as they want, while slaves often received a very small portion of food. Another example he gives is how when cattle are to be sold, they are transported in a way that is comfortable to them. On the other hand, slaves often had to walk very long distances, regardless of the weather, while being chained to each other.
