Answer: people who demanded the emancipation of slaves.
Abolitionism refers to the movement in the United States to end slavery. Abolitionism became particularly strong with Enlightenment, as many thinkers saw slavery as contrary to its ideals.
Immediately after the Revolutionary War, many Northern states passed legislation abolishing slavery. However, the process was slower in Southern states. Prior to the Civil War, abolitionists campaigned for the emancipation of slaves in the South, and as a result of the way, slavery was declared unconstitutional in 1865.
