Movements in the 19th century that sought to abolish slavery worldwide included the abolitionist movement in Britain and the United States, which gained momentum through activism, literature, and political lobbying. Key figures like Frederick Douglass, William Lloyd Garrison, and Harriet Tubman played significant roles in advocating for the end of slavery. The British Slave Trade Act of 1807 and the American Emancipation Proclamation of 1863 were landmark achievements resulting from these efforts. Additionally, international organizations, such as the World's Anti-Slavery Society, worked toward establishing rights and freedoms for enslaved individuals, laying the groundwork for future human rights campaigns.
