Summary: John Brown was an extreme abolitionist, often resorting to violence to make his point rather than peaceful or political methods. He raided the federal arsenal at Harper's Ferry and seized all arms within. His intention was to start an armed uprising of slaves and destroy the establishment of slavery. However, the US Marines, led by Colonel Robert E. Lee, attacked Brown and his allies, killing ten of his men, including two of his sons. Brown was captured, tried for treason and murder, and was executed.
Northern Perspective: The North, in general, agreed with the principles behind the raid. However, most disagreed with the way he went about making his point. There were some that wholeheartedly supported his actions and thought he was a hero.
Southern Perspective: The South, on the other hand, saw Brown as a traitor who committed a vicious attack against their country and their way of life.
