In 1789, a middle-aged African-born man in London published The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa, the African, laying the foundations for new genres of literature and new ways of understanding the experiences of enslaved people. In this autobiography, the author, Olaudah Equiano, detailed his life journey from African captivity to Atlantic slavery to British freedom. In twelve chapters, Equiano presented a body of evidence that helped to support the cause of abolition and the end of transatlantic slaving by Britain and others.
