Who were the main participants of slave trade?

The main participants in the transatlantic slave trade included European colonial powers, such as Portugal, Spain, Britain, France, and the Netherlands, who facilitated the capture and transport of enslaved Africans. African kingdoms and traders also played a crucial role by capturing individuals through warfare or trade and selling them to Europeans. The enslaved individuals were primarily transported from West and Central Africa to the Americas, where they were forced into labor on plantations and in various industries. This brutal trade significantly impacted the Demographics, economies, and cultures of both Africa and the Americas.
