Who is John Brown?

Radical abolitionist John Brown and his sons already had massacred pro -slavery people in Kansas. He escaped the law and then was funded by rich New England abolitionists to incite a slave riot. He took over a Federal arsenal and with the weapons tried to incite a slave revolution. No slaves joined him and he was hanged for treason.

He was a white man who was against slavery. He started a rebellion. And help start the civil war (more or less)
