Explanation:
In the early middle age (around 500 years) Africa´s was still well represented by one of the most iconic and ancient cultures of the world, the <em>Egyptians</em>. Their territory was located in the northside of Africa in the well known Sahara desert, they worshipped pagan gods, until the Romans appeared, and started to spread the Christianism.
The Egyptian social structure was very hierarchized with many floors were different sectors of people were assigned, the Pharaoh first, then nobility, priests, soldiers, scribes, merchants and more, however other cultures, with novelty social structure, and army distribution started to approach (Romans, Islam, etc).
A century and a couple of decades later Africa´s desertic zones were occupied by<em> Islam</em> (around 646), new territories started to be used (<em>Ghana </em>for example) in the continent, and more cultures started to establish settlements.
Due to this activity, the<em> Sahara trade route</em> was founded, the Islam started to have more control and have great power in the area, spreading their religion, and naturally having different conflicts with other kingdoms in order to defend and expand the territory, that was a common event in Medieval times.
