Answer:
Muslims conquered other areas in Africa and cut off Axum from its lucrative trade routes.
Explanation:
The Axum Empire was an African kingdom that was located in northern Africa, close to the Red Sea Coast - Ethiopia, Eritrea, Djibouti, Somalia, and Somaliland -. It was founded in the 1st Century CE and reached its peak to the 6h century CE.
It prospered because the Empire controlled the trade routes that had a high trade of gold and ivory. But when the Muslims conquered the areas which the routes passed, this made the center of the Empire to shift 300km south, this contributed to the decline of the Empire.
