Massachusetts was home to a number of powerful abolitionist and anti-slavery groups during the 18th and 19th centuries, and this fine online exhibition created by the Massachusetts Historical Society brings together a number of primary documents that tell the stories of African Americans and abolitionist movements in the commonwealth. With financial assistance from the Institute of Museum and Library Services, the Society has crafted an exhibition that is divided into a number of thematic sections, including "The Struggle for Freedom", "The Legal End of Slavery in Massachusetts", and "Revolutionary Participation". Each of these sections contains an informative essay, coupled with images of historical documents ranging from receipts for slaves to letters written by various individuals involved in the anti-slavery movement. Visitors will also appreciate such little-seen gems as letters from African Americans who fought in the Revolutionary War.
