Once in sahara how do you trade

Traders moved their goods across the Sahara in large groups called caravans. Camels were the main mode of transportation and were used to carry goods and people. Sometimes slaves carried goods as well. Large caravans were important because they offered protection from bandits.Trade began over the Sahara desert as the Chinese sent out envoys to scope the land.
