Sahelian kingdom

The Sahelian kingdoms were a series of kingdoms or empires that were centered on the sahel, the area of grasslands south of the Sahara. The wealth of the states came from controlling the trade routes across the desert. Their power came from having large pack animals like camels and horses that were fast enough to keep a large empire under central control and were also useful in battle. All of these empires were also quite decentralized with member cities having a great deal of autonomy.

The Sahel states were limited from expanding south into the forest zone of the Ashanti and Yoruba as mounted warriors were all but useless in the forests and the horses and camels could not survive the heat and diseases of the region.

List of the Sahel Kingdoms

*The first major state to rise in this region was the Kingdom of Ghana. Centered in what is today Senegal and Mauritania, it was the first to benefit from the introduction of pack animals by Arab traders. Ghana dominated the region between about 750 and 1078. Smaller states in the region at this time included Takrur to the west, the Malinke kingdom of Mali to the south, and the Songhai centred around Gao to the east.
*When Ghana collapsed in the face of invasion from the Almoravids, a series of brief kingdoms followed, notably that of the Sosso; after 1235, the Mali Empire rose to dominate the region. Located on the Niger River to the west of Ghana in what is today Niger and Mali, it reached its peak in the 1350s, but had lost control of a number of vassal states by 1400.
*The most powerful of these states was the Songhai Empire, which expanded rapidly beginning with king Sonni Ali in the 1460s. By 1500, it had risen to stretch from Cameroon to the Maghreb, the largest state in African history. It too was quite short-lived and collapsed in 1591 as a result of Moroccan musketry.
*Far to the east, on Lake Chad, the state of Kanem-Bornu, founded as Kanem in the 800s, now rose to greater preeminence in the central Sahel region. To their west, the loosely united Hausa city-states became dominant. These two states coexisted uneasily, but were quite stable.
*In 1810 the Fulani Empire rose and conquered the Hausa, creating a more centralized state. It and Kanem-Bornu would continue to exist until the arrival of Europeans, when both states would fall and the region would be divided between France and Great Britain.
