Answer:
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.
