Harpers Ferry Lesson Plan

In this 8th grade U.S. history lesson, students investigate the legacy of John Brown and the 1859 Harpers Ferry raid, a dramatic event that intensified sectional conflict in the years before the Civil War. The lesson is designed for middle school or high school students studying the abolitionist movement, slavery, sectionalism, and the causes of the Civil War.

Students engage with the material by analyzing images, short abolitionist biographies, a level-setting video, and primary sources from Northern and Southern perspectives. Through these sources, students investigate what abolitionists believed, why Brown’s raid caused national alarm, and how the Congressional investigation into the raid highlighted deepening conflict between the North and South.

By the end of the lesson, students will be able to use images of Brown from throughout U.S. history to create an argument answering the Compelling Question “What is John Brown’s legacy?”

  • Lesson plan
    • Students describe the beliefs of abolitionists, and through reading and discussion explain why John Brown’s raid caused national alarm, and prompted a Congressional inquiry. Students are asked to pick an image of John Brown from a curated collection, and end the lesson by presenting an argument about why their selected image best represents his legacy in U.S. history.
  • Primary and Secondary Sources
  • Student Worksheets
    • Student worksheets that help learners define abolitionism, compare viewpoints, and explain why Congress investigated Brown’s raid.
    • Compelling Question handout – an assessment tool where students use evidence to decide which image best represents John Brown’s legacy.
    • Taking Informed Action handout – an extension activity that asks students to apply historical image analysis to a modern public figure.
  • Answer Key
    • Teacher support materials that provide guidance for student responses and class discussion. Includes a completed key that contains evidence-based sample answers, and suggested responses for discussion questions.

In this lesson, students explore how John Brown’s raid and the subsequent Congressional investigation by the Mason Committee revealed deep national divisions over slavery. They consider the following questions:

  • What is an abolitionist?
  • Why did Congress investigate John Brown’s raid?
  • What is John Brown’s legacy?

These questions help students connect primary source analysis to the larger issue of sectional conflict before the Civil War.

What Happened at Harpers Ferry?

In the decades before the Civil War, the United States became increasingly divided over slavery. Abolitionists argued that slavery was morally wrong and should end, and used a variety of methods for opposing it. Some used speeches, newspapers, books, and political organizing, while others assisted enslaved people escaping through the Underground Railroad. John Brown took a more radical approach, believing that slavery could only be destroyed through armed resistance.

In October 1859, Brown and a small group of followers attacked the federal armory at Harpers Ferry, Virginia. Brown hoped to seize weapons and inspire a larger revolt by enslaved people. The raid failed, Brown was captured, and he was later executed. However, the event created shock across the country. Many Southerners feared that Brown was but the first of a gathering storm of abolitionists who would encourage violent servile rebellion, while some Northerners viewed Brown as a martyr for the anti-slavery cause.

Congress, led by Senator James Mason, investigated the raid with three primary goals: to determine whether Brown had acted alone, whether he had intended to undermine the United States, from whence he had received his weapons, and whether a larger anti-slavery network had supported him. The majority and minority reports from the investigation revealed the sectional tensions of the time: Southern-aligned voices emphasized danger, violence, and probable Northern complicity, while Northern-aligned voices pushed back against the idea that abolitionists or free states were broadly responsible for Brown’s actions. The investigation showed how the raid became a symbol of the nation’s growing conflict over slavery, and the increasingly intractable nature of the slavery debate.

Content Standards

This lesson aligns with Michigan social studies content standards and supports U.S. history instruction by helping students analyze abolitionism, sectional conflict, congressional investigation, and historical memory through primary sources, visual media, and evidence-based writing.
