The rise of the Kanem-Borno Empire in the 9th century was primarily due to the control of trans-Saharan trade routes. The location of the Kanem-Borno Empire was strategic as it was situated in a region that connected the North African trade networks with Sub-Saharan Africa. This allowed the empire to become a critical hub for traders passing through these routes. Through controlling these trade routes, the Kanem-Borno Empire was able to collect taxes and tariffs, accumulating wealth that was crucial for its growth and stability.

The trans-Saharan trade routes facilitated the exchange of valuable goods such as salt, gold, and slaves. These goods were in high demand, making the trade routes highly valuable. By dominating these routes, the Kanem-Borno Empire could ensure they benefited economically, which contributed significantly to their power and influence in the region.

The wealth generated from this trade was used to strengthen and expand the empire's infrastructure, military, and influence. This, in turn, allowed for the sustained growth of the empire and enabled it to engage in further diplomatic relations and sometimes conquests, contributing to its overall prominence and durability throughout history.
