Mixing idealism with violence, abolitionist John Brown cut a wide swath across the United States before winding up in Virginia, where he led an attack on the U.S. armory and arsenal at Harpers Ferry. Supported by a “provisional army” of 21 men, Brown hoped to rouse the slaves in Virginia to rebellion. But he was quickly captured and, after a short but stormy trial, hanged on December 2, 1859.

Brian McGinty provides the first comprehensive account of the trial, which raised important questions about jurisdiction, judicial fairness, and the nature of treason under the American constitutional system. After the jury returned its guilty verdict, an appeal was quickly disposed of, and the governor of Virginia refused to grant clemency. Brown met his death not as an enemy of the American people but as an enemy of Southern slaveholders.

Historians have long credited the Harpers Ferry raid with rousing the country to a fever pitch of sectionalism and accelerating the onset of the Civil War. McGinty sees Brown’s trial, rather than his raid, as the real turning point in the struggle between North and South. If Brown had been killed in Harpers Ferry (as he nearly was), or condemned to death in a summary court-martial, his raid would have had little effect. Because he survived to stand trial before a Virginia judge and jury, and argue the case against slavery with an eloquence that reverberated around the world, he became a symbol of the struggle to abolish slavery and a martyr to the cause of freedom.

On the 150th anniversary of the death of the English historian and politician Thomas Babington Macaulay, Robert Sullivan offers a portrait of a Victorian life that probes the cost of power, the practice of empire, and the impact of ideas.

His Macaulay is a Janus-faced master of the universe: a prominent spokesman for abolishing slavery in the British Empire who cared little for the cause, a forceful advocate for reforming Whig politics but a Machiavellian realist, a soaring parliamentary orator who avoided debate, a self-declared Christian, yet a skeptic and a secularizer of English history and culture, and a stern public moralist who was in love with his two youngest sisters.

Perhaps best known in the West for his classic History of England, Macaulay left his most permanent mark on South Asia, where his penal code remains the law. His father ensured that ancient Greek and Latin literature shaped Macaulay’s mind, but he crippled his heir emotionally. Self-defense taught Macaulay that power, calculation, and duplicity rule politics and human relations. In Macaulay’s writings, Sullivan unearths a sinister vision of progress that prophesied twentieth-century genocide. That the reverent portrait fashioned by Macaulay’s distinguished extended family eclipsed his insistent rhetoric about race, subjugation, and civilizing slaughter testifies to the grip of moral obliviousness.

Devoting his huge talents to gaining power—above all for England and its empire—made Macaulay’s life a tragedy. Sullivan offers an unsurpassed study of an afflicted genius and a thoughtful meditation on the modern ethics of power.

When John Brown led twenty-one men in an attack on the federal arsenal at Harpers Ferry on October 16, 1859, he envisioned a biblical uprising of millions of armed bondsmen, thus ridding the nation of the scourge of slavery. The insurrection did not happen, and Brown and the other surviving raiders were quickly captured and executed. This landmark anthology, which collects contemporary speeches, letters, newspaper articles, journals, poems, and songs, demonstrates that Brown’s actions nonetheless altered the course of American history.

John Stauffer and Zoe Trodd have assembled an impressive and wide-ranging collection of responses to Brown’s raid: Brown’s own words, northern and southern reactions, international commentary, and reflections from the Civil War and Reconstruction era. Represented here are all the figures one would expect to see (Lincoln, Thoreau, Frederick Douglass), many surprises (John Wilkes Booth, Karl Marx, Giuseppe Garibaldi), as well as free and enslaved blacks and white citizens. The result is a book that views Brown from multiple vantage points.

The Introduction describes the panic that Harpers Ferry created in the South, splitting the Democratic Party along sectional lines and altering the outcome of the 1860 presidential election. Without Brown, it speculates, the Civil War and emancipation would have been delayed by another four years—probably more—which in turn might have disrupted emancipation movements in Brazil, Cuba, and even Russia. The Tribunal is essential reading for anyone interested in the Civil War era and the history of social protest movements.
