The Luba-Lunda states eventually declined as a result of both Atlantic slave trade in the west and Indian Ocean slave trade in the east and wars with breakaway factions of the kingdoms. The Chokwe, a group that is closely related to the Luvale and formed a Lunda satellite state, initially suffered from the European demand for slaves, but once they broke away from the Lunda state, they themselves became notorious slave traders, exporting slaves to both coasts.
