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.
