Answer: Tran Saharan trade linked North Africa and the Mediterrean world with West Africa.
Explanation: The Trans-Saharan trade network is a network of trade routes that connect North Africa with sub-Saharan Africa across the Saharan deserts. Historically, this was the most active land-based trade network in Africa. While trade across the Sahara existed before recorded history, peak trade on the routes was between the 8th and 17th centuries.
The Saharan desert is the world's largest desert. Trans-Saharan trade began for the same reason as other global exchange networks– the desire for goods unavailable in buyers’ home regions. As time went on, improvements in commercial practices and technological innovation allowed the amount of trade to increase.
The Earliest Trade Across the Sahara Was in Gold and Salt
One of the earliest causes of the trade was the exchange of gold and salt. West Africa had large quantities of gold but lacked access to salt. In contrast, North Africa had abundant supplies of salt but scarce supplies of gold. Rulers in North Africa, Europe, and the Middle East wanted gold. And because salt is essential in sustaining human life, West Africans could not live without salt. This scarcity created an incentive to trade across the harsh desert environment. Over time, traders began moving wider varieties of goods across the routes.
Trans-Saharan trade rapidly increased after the introduction of camels from Central Asia to North Africa. The camel's biology was well suited for crossing long distances with little water while carrying heavy cargo.
Camel saddles were significant technological innovations that allowed merchants to utilize camels to move people and goods. Different African and Eurasia societies continually improved camel saddles to increase the weight camels could carry. Heavier loads meant merchants could transport more goods, which lowered costs and increased profits. Hope this was helpful
