The movement aimed at ending the transatlantic slave trade in the 19th century was known as the abolitionist movement. Activists and reformers campaigned vigorously against the inhumane practice of slavery and the trade that supported it. This movement emerged in various countries, with notable figures such as William Wilberforce in Great Britain, Frederick Douglass in the United States, and many grassroots organizations advocating for social change. The moral arguments against slavery, along with economic factors and changing social attitudes, led to increasing awareness and support for abolition. The movement ultimately resulted in legal changes, such as the British Slavery Abolition Act of 1833.
