How were the west African kingdom involced in slave trade?

West African kingdoms played a significant role in the transatlantic slave trade by capturing and trading enslaved individuals from rival tribes and communities. They often engaged in warfare or raids to acquire captives, whom they sold to European traders in exchange for goods such as firearms, textiles, and alcohol. These kingdoms, including the Ashanti, Dahomey, and Oyo, benefited economically from the trade, which deeply impacted their societies and contributed to the destabilization of the region. The involvement of these kingdoms in the slave trade also facilitated the expansion of European colonial interests in Africa.
