Overview, West Africa and the rise of the Songhai Empire

West Africa is home to many of Africa's oldest kingdoms. These kingdoms played an important role in the development of trade and economic growth of the region. As old kingdoms came to be replaced by new smaller ones many changes were experienced. The transformations were influenced by conquest and warfare along with patterns of trade. West African societies were shaped by competition for wealth and the search for independence from more powerful kingdoms.

The earliest African civilizations south of the Sahara desert were in West Africa. These civilisations developed at a time when most of Europe was experiencing the Dark Age, after the fall of the Western half of the Roman Empire around 476 A.D. the people of West Africa could already smelt iron ore to make tools for warfare and agriculture. Iron farming tools made agricultural methods far more efficient. This led to improvements in agriculture and greater productivity of the land, as prosperity grew the population expanded giving rise to larger towns. Broad rivers linked people in these larger towns by way of canoe travel. These rivers also maintained the fertility of the soil all year round.

At the same time kingdoms were developing in this region. One of the earliest kingdoms to emerge here was ancient Ghana to the far West. By the year 300 A.D, this kingdom had been ruled by about 40 kings, showing that its political administration was well developed to allow new kings to take office without destroying the kingdom by fighting destructive civil wars. The economy of Ghana was based on iron and gold mining along with agriculture. Products were traded with Berber societies north of the Sahara desert. At the same time (1230-1300) the Mali kingdom of the Mande people, to the east of Ghana, was growing and increasing its control of trade in the region. This brought the two kingdoms into conflict. Finally, the Ghana kingdom was taken over by the Mali kingdom. The Mali kingdom was able to establish its influence with ease due to the surrounding savannah terrain. This enabled the easy and speedy dispatch of soldiers across the region to conquer neighbours. The adoption of the Islamic faith by the Mali people in about the 1500s during the rule of Kankan Musa, created a point of unity for this kingdom.

Quarrels over who should succeed the throne and rebellion by the Fulani people in Senegambia and the Songhai people in Gao led to the collapse of the Mali kingdom in the 16th century. Songhai became independent of Mali, and rivalled it as the leading power in West Africa.

Culture, Religion and Monarchy

The Songhai had settled on both banks of the middle Niger River. They established a state in the 15th century, which unified a large part of the western Sudan and developed into a brilliant civilisation. It was ruled by the dynasty or royal family of Sonni from the thirteenth century to the late fifteenth century. The capital was at Gao, a city surrounded by a wall. It was a great cosmopolitan market place where kola nuts, gold, ivory, slaves, spices, palm oil and precious woods were traded in exchange for salt, cloth, arms, horses and copper.
