Just compare a river map of West Africa to a map of West African kingdoms.
You can clearly see that all of these kingdoms form around the Niger River.
More support to this: None of these other rivers are even in Africa: The Thames is in England, the Indus is in Pakistan, and the Euphrates runs through the Middle East.
That is The Federal Reserve Board it Determines the direction of monetary policy.
Black Sea, the Black Sea has Russia's warm water port.
I hope this helps! :)
