John Brown

Radical Abolitionist

Harper’s Ferry, Virginia

Brown’s Martyrdom

“If it is deemed necessary that I should forfeit my life for the furtherance of the ends of justice, and mingle my blood further with the blood of my children and with the blood of millions in this slave country whose rights are disregarded by wicked, cruel, and unjust enactments,--I submit, so let it be done!”

John Brown, 1859

Summary

• Expansionist ambition and Manifest Destiny re-energized the debate over slavery’s expansion

• Maintaining a balance between free states and slave states was seen as one way to keep the Union together

• These compromises resolved the issue temporarily, not permanently
