John Brown (abolitionist) John Brown (May 9, 1800 â December 2, 1859) was an American abolitionist who believed armed insurrection was the only way to overthrow the institution of slavery in the United States. Brown first gained attention when he led small groups of volunteers during the Bleeding Kansas crisis of 1856.

John Brown's mission at Harpers Ferry did not immediately achieve his goals, but the legacy of the raid rang throughout the country. John Brown's quest to end slavery in America did not begin, nor end with the raid on Harpers Ferry. To understand the complicated crusader, one must begin by looking at the events that defined John Brown's life.
