The expansive arid region spanning much of North Africa significantly influenced historical patterns in the continent and beyond. It acted as both a barrier and a conduit for trade, migration, and cultural exchange. The desert’s presence shaped settlement patterns, concentrating populations along its fringes and in oases, and drove innovation in transportation and resource management.
Its formidable nature presented significant challenges, impacting the development of states and societies. However, trans-Saharan trade routes, facilitated by innovations like the camel saddle, connected sub-Saharan Africa with the Mediterranean world and the Middle East. This exchange facilitated the movement of goods such as gold, salt, and enslaved people, as well as the spread of ideas and religions like Islam. The control of these trade routes often led to the rise of powerful empires and kingdoms in West Africa, such as Ghana, Mali, and Songhai.
