What continents were involved in the Atlantic slave trade?

The Atlantic slave trade primarily involved three continents: Africa, Europe, and the Americas. Enslaved Africans were forcibly taken from their homelands and transported across the Atlantic Ocean to the Americas, where they were sold into slavery. European nations, particularly Portugal, Spain, Britain, France, and the Netherlands, played significant roles in capturing, transporting, and profiting from this trade. The trade profoundly impacted the societies and economies of all three continents involved.
