Anti-slavery refers to the movement and ideology that opposes the practice of slavery, advocating for the freedom and rights of enslaved individuals. This movement gained significant momentum in the 18th and 19th centuries, particularly in Europe and North America, where activists worked to abolish slavery and promote human rights. Key figures in the anti-slavery movement include Frederick Douglass, an escaped slave who became a prominent abolitionist, and Harriet Tubman, who helped many enslaved people escape through the Underground Railroad. The efforts of these individuals and many others contributed to the eventual abolition of slavery in various countries.
