The 19th-century movement aimed at ending slavery in the United States was known as the Abolitionist Movement. This movement gained momentum in the early to mid-1800s, advocating for the emancipation of enslaved people and the eradication of slavery. Abolitionists included notable figures such as Frederick Douglass, Harriet Tubman, and William Lloyd Garrison, who used speeches, writings, and activism to raise public awareness and influence legislative change. The movement ultimately contributed to the Civil War and led to the passage of the 13th Amendment, which abolished slavery in the United States.
