The correct answer is John Brown, an extreme abolitionist, tried to end te entire institution of slavery by attacking a federal armory in hopes to arm slaves in 1859- the raid failed.
John Brown was a strong abolitionist who became involved in this movement shortly after the Kansas-Nebraska Act. John Brown got a first hand look at how the issue of slavery has caused violence and immorality in American society. This is why he dedicated the rest of his life to getting rid of the institution.
This also helps to explain why he raided Harper's Ferry. He believed that raiding this arsenal and taking the weapons would allow him to assemble a great enough military force to free slaves and destroy the system in the Southern states completely.
