The movement that sought to eliminate slavery in the United States is known as the abolitionist movement. This social and political campaign gained momentum in the early to mid-19th century, driven by moral, religious, and political arguments against slavery. Abolitionists included former slaves, activists, and prominent figures such as Frederick Douglass, Sojourner Truth, and Harriet Tubman, who advocated for immediate emancipation and suffrage for African Americans. The movement galvanized public opinion, leading to increased tensions between Northern and Southern states. Ultimately, it laid the groundwork for significant legislative changes, culminating in the Emancipation Proclamation in 1863 and the Thirteenth Amendment, which abolished slavery in the U.S.
