Who used violence to try to end slavery?

Lucy Stone

Harriet Beecher Stowe

John Brown

Henry Clay

the correct answer is John Brown!

Explanation:

John Brown was a radical abolshonist in USA during the 19th centur ywho fiercely believed that slavery must end in United States either peacefully through dialogue and consensus or through force and aggression.

he chose the latter one and believed that violence can be used to end slavery.

he led a small group of people to raid a federal armory in Harpers Ferry, Virginia (now West Virginia), trying to start an armed slave revolt in USA!

the raid was a failure and ended up with 7 people killed and Brown was executed by hanging in 1859.

the effect of the ming leaders banning ships with more than two masts was that there was no further construction of ships masts, because there was a surplus. ming emperors disallowed foreign exploration
