The movement of the 19th century that sought to abolish slavery, particularly in the United States, was the abolitionist movement. This movement aimed to end the practice of slavery and promote equal rights for enslaved individuals. It gained momentum through the efforts of various activists including Frederick Douglass, Harriet Tubman, and William Lloyd Garrison, who used literature, speeches, and underground railroads to raise awareness. The movement was instrumental in establishing moral and political arguments against slavery, culminating in the Civil War and eventually leading to the emancipation of enslaved people following the passage of the 13th Amendment in 1865.
