170 years ago, the Fugitive Slave Act was passed by the United States Congress and signed into law by President Millard Fillmore. Every American citizen was now expected to be a slave catcher, and no African American in the North was safe from the threat of being sent back to enslavement. Concord itself had its share of Radical abolitionists, and men and women with the family names of Emerson, Thoreau, and Alcott, along with many others, stood up to fight what they considered an immoral law. Join Concord Historian Richard Smith as he tells the story of Concord and the Fugitive Slave Law.
