Answer: True
Explanation: True: John Brown was a radical abolitionist who supported slave uprising and rebellion to prevent the use of slavery. He and his sons sadistically attacked five pro slavery men in Pottawatomie, Kansas in response to a pro slavery attack on free-soil land in Lawrence, Kansas. Later, John Brown attempted to start a slave insurrection by providing Virginian slaves with weapons, encouraging them to turn against their slave-masters.
