The movement that sought to end the practice of slavery in the 18th and 19th centuries is known as the Abolitionist Movement. It included various socio-political campaigns, literature, and activism aimed at ending slavery, particularly in the United States and Britain. Key figures included Frederick Douglass, Harriet Tubman, and William Wilberforce. The movement was fueled by moral, religious, and economic arguments against the institution of slavery, advocating for the rights and freedoms of enslaved individuals. The efforts contributed to significant legislative changes, including the Emancipation Proclamation in the U.S. and the Slavery Abolition Act in Britain.
