The leading figure in the Abolitionist Movement in the United States was Frederick Douglass. Born into slavery, he escaped and became a powerful orator, writer, and activist advocating for the end of slavery and equal rights for African Americans. Douglass's speeches and writings, particularly his autobiography, *Narrative of the Life of Frederick Douglass*, exposed the harsh realities of slavery and articulated the quest for freedom and justice. He played a crucial role in advocating for the 13th Amendment, which abolished slavery in the U.S. Douglass's legacy as a champion of human rights continues to inspire future generations.
