The end of slavery in Black history refers to the abolition of slavery in the United States, which officially occurred with the ratification of the 13th Amendment to the U.S. Constitution on December 6, 1865. This amendment declared that "neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction."

The end of slavery was the culmination of decades of resistance and activism by enslaved African Americans, free blacks, abolitionists, and other allies who fought tirelessly to bring an end to the institution of slavery in the United States. The Civil War (1861-1865) played a pivotal role in the abolition of slavery, as it led to the emancipation of enslaved people in Confederate-held territories through President Abraham Lincoln's Emancipation Proclamation in 1863.

After the 13th Amendment was ratified, formerly enslaved individuals began the challenging process of rebuilding their lives and communities in the aftermath of slavery. This period, known as Reconstruction, was marked by significant advancements in civil rights and political participation for African Americans, including the passage of the 14th and 15th Amendments, granting citizenship and voting rights to Black men.

The end of slavery represents a critical milestone in Black history, marking the beginning of a long and ongoing struggle for equality, justice, and freedom for African Americans in the United States. Despite the abolition of slavery, systemic racism and discrimination persisted, leading to the continued fight for civil rights and social justice in the years that followed.
