The document discusses the decline of the slave trade, noting that:
1) Europeans traded African slaves to gain profit and power, seeing it as the easiest way to accumulate wealth and strengthen their empires.
2) The Atlantic slave trade was the largest forced migration in history and part of the triangular trade route between three continents. Ships from Europe traded goods for African slaves, who were then brought to the Americas.
3) Abolitionist movements grew in the late 18th century, influenced by ideals of liberty, equality, and human rights emerging from the Enlightenment and American Revolution. Parliament banned the slave trade in 1807.
