Sahel: This is a geographic zone in Africa that serves as a transition between the Sahara desert in the north and the Sudanian Savanna in the south. It's like an environmental bridge connecting two vastly different landscapes.
Atlantic Slave Trade: This was an infamous period from 15th to 19th centuries when millions of Africans were captured and transported across the Atlantic Ocean to work as slaves in Europe, America, and Caribbean plantations. Imagine it as one of history's darkest chapters where human beings were treated like commodities.
Colonialism: The policy or practice by which a powerful country directly controls less powerful countries and uses their resources to increase its own power and wealth. Picture this as if someone took over your house without your permission, used all your stuff for their benefit while you got nothing or very little in return.
