Maritime history exhibit

The Commonwealth Museum in the Massachusetts Archives building, Columbia Point, is displaying “From Slavery to Freedom: African Americans and Maritime History” now through May 26.

The sea played a significant role in the history of African-Americans. It was a source of misery on the dangerous passage from Africa to the new world, but by the 19th century Massachusetts had become an important center of the abolitionist movement. Seaport communities became avenues of escape for fugitive slaves and a source of employment, especially in the whaling port of New Bedford.

This exhibit traces important themes in maritime history that have often been hidden
