In his biography, Equaino wrote about his kidnapping in Nigeria and his horrifying experiences on a slave ship crossing the Atlantic.
Recent research has cast doubt on Equaino's origin story, as two documents place his birth in America, but nevertheless, he told a story that got many Britains to sympathise with the plight of the slaves. His work is seen as one of the many factors that ended the Britisch slave trade a few years after his death.
The painting from aroubd 1760 was long believed to be Equiano. Now some historians believe it might be Charles Sanches, the first African to vote in Britain.
