The empires of Ghana, Mali and Songhai were located in areas that were conducive to the development of great empires. These empires covered a large extension of land with very different weather and ecosystems, including the Sahara desert and the thick jungles south of the Niger River.

Moreover, the empires benefitted from the trans-African trade, having an open route to the markets of Europe and the world.
