Background
Enslaved people had resisted bondage from its beginnings, and free and formerly enslaved Black Americans had long attacked slavery. In the 1820s and 1830s a more visible interracial network of local and national societies, churches, newspapers, lecturers, and vigilance committees pressed for immediate nationwide abolition amid westward expansion and intensifying sectional conflict.

Course

They faced mob violence and censorship while confronting the Fugitive Slave Act, the expansion of slavery, and the political crises that led to the Civil War.

Outcome
Enslaved people who fled, resisted, and joined Union forces helped turn the Civil War into a war for emancipation. The Thirteenth Amendment abolished slavery in 1865, fulfilling the movement's central legal goal, although many abolitionist organizations then divided over whether their work was complete.

Historical significance
Abolitionism made slavery a sustained national political crisis and provided models for later organized reform. Haiti's successful antislavery revolution inspired Black activists and alarmed slaveholders, but ending slavery did not itself secure equal citizenship: Black abolitionists continued struggles for voting, civil rights, and protection from racial violence after 1865.
