Answer:
Step-by-step explanation:
Western Africa was closer to the Americas than the more southernmost areas and had sea ports where the enslaved people could be picked up. This ease of access to the enslaved made West Africa an ideal destination for slave traders.
Kingdoms in West Africa were also willing to cooperate with slave traders to make a profit by selling enslaved people. They saw this as an alternative source of income and used the trade to gain access to European made goods.
