The movement that sought to end the transatlantic slave trade in the 19th century is known as the abolitionist movement. This movement comprised various social and political efforts aimed at stopping the trade of enslaved Africans and ultimately abolishing slavery itself. Key figures, such as William Wilberforce in Britain, campaigned through public awareness, moral arguments, and political advocacy. The movement gained significant momentum in the early 1800s, resulting in many countries passing laws against the slave trade and eventually leading to the emancipation of enslaved peoples.
