The movement to end slavery in the United States is commonly referred to as the Abolitionist Movement. It emerged in the early 19th century, driven by various activists, both black and white, who fought against the institution of slavery basing their arguments on moral, economic, and humanitarian grounds. Key figures such as Frederick Douglass, Sojourner Truth, and Harriet Tubman played pivotal roles in promoting the cause. The movement culminated in the Civil War, after which the Thirteenth Amendment abolished slavery in 1865. Its effects are profound, contributing to civil rights advancements in subsequent decades.
