Explanation: The Ghana Empire, properly known as Wagadou (as Ghana was the title of its ruler), was a West African empire located in the area occupied by present-day southeastern Mauritania and western Mali. Although complex societies based on trans-Saharan trade in salt and gold had existed in the region for centuries, the introduction of the camel to the western Sahara in the 3rd century CE, opened the way to great changes in the area that eventually became the Ghana Empire.
