Abraham Lincoln is the U.S. president most famously associated with the abolition of slavery.

By prioritizing the preservation of the Union and the eradication of the institution of slavery, Lincoln fundamentally transformed the American social and political landscape, ensuring that the practice was legally prohibited across all states following the conclusion of the Civil War.

The American Civil War was a major conflict fought between the Northern states (the Union) and the Southern states (the Confederacy) from 1861 to 1865.

Abraham Lincoln, the 16th President of the United States, is the central figure associated with the abolition of slavery. During the American Civil War, he issued the Emancipation Proclamation in 1863, which declared that all enslaved people in Confederate-held territory were to be set free.
