What were the African kingdoms that provided slave labor to the Americans?

Several African kingdoms were involved in the transatlantic slave trade, supplying enslaved individuals to the Americas. Prominent among these were the Kingdom of Dahomey, the Ashanti Empire, and the Oyo Empire, which actively engaged in capturing and trading enslaved people. Additionally, the Kingdom of Kongo and various smaller tribes and chiefdoms also participated in the trade, often exchanging enslaved individuals for goods like firearms and textiles. This complex network contributed significantly to the forced migration of millions of Africans to the Americas.
