12 Years a Slave is a 2013 period drama film and an adaptation of the 1853 slave narrative memoir Twelve Years a Slave by Solomon Northup, a New York State-born free African-American man who was kidnapped in Washington, D.C., in 1841 and sold into slavery. Northup worked on plantations in the state of Louisiana for 12 years before his release. The first scholarly edition of Northup's memoir, co-edited in 1968 by Sue Eakin and Joseph Logsdon, carefully retraced and validated the account and concluded it to be accurate. Other characters in the film were also real people, including Edwin and Mary Epps, and Patsey.
