a. “Trans-Saharan trade networks had a minimal effect on the formation of new states in West Africa between 1200 and 1450 CE. By 1200, and before large-scale trade occurred across the Sahara, many states had already formed in the region. In addition, complex societies caused an increased need for trade and led to the development of trade networks in West Africa.” b. “The trans-Saharan trade networks influenced the ways new states formed in West Africa.

The trade networks involved well-known cities in West Africa, such as Timbuktu.” Consider the two thesis options. Which would not be an acceptable thesis for the prompt?
