Twelve Years a Slave is the true story of Solomon Northup: born a free black man in New York State, and sold into slavery after being tricked in 1841. Unable to convince anyone he is not a slave, Solomon spent 12 years in bondage, before finally being set free. Northup’s memoir, recounting details of the slave markets and the harsh life on plantations, was used in the struggle to abolish slavery in the United States.
