Abolition in Black history refers to the movement to end slavery in the United States, which was led primarily by African Americans and their allies in the 18th and 19th centuries. The abolitionist movement gained momentum in the 1830s and 1840s with the formation of organizations such as the American Anti-Slavery Society and the Underground Railroad.

Prominent African American abolitionists such as Frederick Douglass, Harriet Tubman, and Sojourner Truth played key roles in the movement by speaking out against slavery, writing narratives about their experiences, and helping enslaved individuals escape to freedom. These activists also worked alongside white abolitionists like William Lloyd Garrison and Harriet Beecher Stowe to push for the abolition of slavery through political activism, legal challenges, and moral persuasion.

The culmination of the abolitionist movement came with the passage of the 13th Amendment to the U.S. Constitution in 1865, which formally abolished slavery in the United States. This achievement was a significant victory for Black Americans and marked a major turning point in the nation's history.

Despite the abolition of slavery, the fight for racial equality and justice continued in the years that followed, leading to the civil rights movement of the 20th century and ongoing efforts to address systemic racism in the United States today. Abolition in Black history serves as a powerful reminder of the resilience, determination, and courage of those who fought for freedom and equality for all.
