The SAHEL REGION is a belt of up to 1,000km wide that spans the 5,400 km in Africa, from the Atlantic Ocean to the Red Sea...
"The wealth of the States came from controlling the trade routes across the desert. Their power came from having large pack animals like camels and horses that were fast enough to keep a large empire under central control and were also useful in battle. The Sahel states were limited from expanding South in the Forest Zone of the Ashanti and Yoruba as mounted warriors were all useless in the forests and the horses and camels could not survive the heat and diseases of the region." ( yes, ask me about it!)
These lovely friendly Ranch horses came from the North Cameroon area of the Sahel region and have adapted well.
