Context_1 : John Brown (May 9, 1800 – December 2, 1859) was an American abolitionist who believed and advocated that armed insurrection was the only way to overthrow the institution of slavery in the United States.

Dissatisfied with the pacifism of the organized abolitionist movement, he said, "These men are all talk. What we need is action—action!" During the Kansas campaign, Brown commanded forces at the Battle of Black Jack and the Battle of Osawatomie.
