What were the roles of African kingdoms in the Atlantic Slave Trade?

The African kingdoms played various roles in the Atlantic Slave Trade. Some kingdoms actively participated in capturing and enslaving Africans, while others acted as middlemen, facilitating the trade by capturing and selling slaves to European traders. Additionally, some African kingdoms benefited economically from the trade by exchanging slaves for goods and weapons. However, it is important to note that not all African kingdoms participated in the slave trade, and many resisted or opposed it.
