Further explanation:

John Brown (1800-1859) was an abolitionist who supported armed struggle against existing laws and government in order to end slavery.  In October 1859, Brown led a raid on the federal armory at Harpers Ferry, Virginia.  The intent was to arm slaves to fight for their freedom and set in motion a slave revolt that would spread across other regions in the South.  The effort was unsuccessful and Brown was hanged for treason against Virginia.
