The major outcome of the abolitionist movements in the U.S. during the 19th century was the emancipation of enslaved people and the eventual abolition of slavery. Driven by moral, religious, and humanitarian beliefs, abolitionists like Frederick Douglass, Harriet Tubman, and William Lloyd Garrison worked tirelessly to raise awareness about the injustices of slavery. Their efforts culminated in the passing of the 13th Amendment in 1865, which abolished slavery throughout the United States. The abolition movement not only transformed the lives of millions but also set the stage for future civil rights initiatives, making the struggle for equality a central focus of American society.
