John Brown Born

Abolitionist John Brown was born in Torrington, Connecticut. His militant opposition to slavery, culminating in the 1859 raid on Harpers Ferry, deepened the national crisis over slavery and made him one of the most polarizing figures of the antebellum era.

Why It Matters

Brown's actions forced the nation to confront the moral crisis of slavery, accelerating the march toward civil war and raising enduring questions about the relationship between conscience, law, and justice.
