Answer:
Countries in West Africa willing entered trade with the Portuguese while countries in East Africa tried to distance themselves from the Portuguese.
Explanation:
The Transatlantic slave trade began during the 15th century when the Portuguese reached Africa, the demand only grew when the Portuguese reached South America. Portuguese started kidnapping people to transform them into slaves, but later they started a trade network in West Africa with African nobles and slavers, there they built forts at Cape Blanco, Sierra Leone, and Elmina.
In East Africa, things were different, for centuries they established a trade network with the Arabs. When the Portuguese reached East Africa, they demanded that the Muslims accepted the rule of the Portuguese King, which they refused to do. The Portuguese destroyed the cities, they built fortresses that made it possible for the Portuguese to control trade in that region.
