Brainliesttt ! how did trade lead to the rise of the sudanic states?

The Sudanic states had massive stocks of gold and with it they traded it across the Sahara. The new trade route came about when the camels were discovered to be able to traverse the vast emptiness of the desert. Most of these tribes already had stable economies from agriculture and fishing, but now they could trade goods like gold, horses, and other precious metals across the Sahara, which they had a monopoly on.

Exchange (trade) is the genuine reason for the improvement and rise of the extraordinary West African kingdoms of Ghana, Mali, and Songhai, and for this reason they are frequently alluded to as the exchanging (trade) states, or exchange kingdoms. The more individuals on both sides of the exchange (trade) were presented to modern merchandise, the more they needed. And the agents certainly profited. The trade goods helped them develop faster. It also helps them to gain knowledge and experiences that will help the people in these states flourish and grow.
