Publisher Description
"With impressive scholarly sleuthing and a storyteller's eloquence, Danielle Allen has written a landmark book about the people and the ideas that changed the world. By bringing the glamorous Duke of Richmond back to life, Allen paints a panoramic portrait of how principles of human equality and the spirit of independence suffused the Atlantic world in the eighteenth century--a story that shapes us still." —Jon Meacham
An explosive, deeply revisionist work that reveals how a renegade English Duke and Thomas Paine, the firebrand polemicist, almost brought the American Revolution to Britain.
When Danielle Allen unearthed a parchment of the Declaration of Independence buried away in Sussex, England, little did she know that she had discovered a story of historical magnitude that would alter our understanding of British and American history. Revealing that the Age of Revolution began earlier than we thought—not with the Boston patriots nor with the Parisian Jacobins, but in Britain itself—Allen demonstrates in Radical Duke that the rights of man, the theory of revolution, and calls for popular sovereignty all emerged from the radical energies of London before they spread across the Atlantic and the Channel.
At the center of this new age was Charles Lennox, the progressive Third Duke of Richmond, a rarely cited historical figure who becomes the biographical focus of Allen’s groundbreaking work. Even with royal blood coursing through his veins, the handsome, gallivanting Duke (1735–1806) preferred to rub shoulders with ordinary folk—supporting the rights of jurors, freedom of the press, and religious toleration. As Allen shows, from 1767 to 1782, he was England’s leading voice of opposition to the Crown, and, as the leader of the Sussex militia, even a threat to the King’s power. But the Duke did not challenge the Crown
alone. The archives have long hidden the covert alliance between the young Duke and his age-mate Thomas Paine, the future author of Common Sense. While working as an obscure tax collector, Paine was engaged by the Duke to contribute to the most influential but anonymous newspaper essays of the age, The Letters of Junius, which spawned sedition trials, defined the rights of man, and brought England to the brink of revolution. Along with a small cadre of radicals, Paine and the Duke fired hearts across two continents and secretly stoked a burgeoning political movement.
Throughout Radical Duke, Allen sets the record straight. Through archival evidence, confirmed with computational tools, she reveals the anonymous authors of the inflammatory Junius letters; she also identifies a new Paine work, his first book, The Juryman’s Touchstone, cowritten in 1771. In the end, the Duke swerved. He did not advocate the overthrow of the monarchy but remained loyal to both Crown and people, launching an age of reform. With her penetrating prose, Allen resuscitates a seminal political figure who has been egregiously neglected throughout history.
APPLE BOOKS REVIEW
Political historian Danielle Allen upends our understanding of the roots of the American Revolution with this fascinating biography of a very important person you’ve almost certainly never heard of. Charles Lennox, the Third Duke of Richmond, was a British aristocrat who openly sympathized with the revolutionary aims of the American colonists. He even campaigned for sweeping democratic reforms at home, including authoring a bill in the House of Lords to give all men the right to vote. All this, and he was also widely considered the most gorgeous man in all of Britain. As Allen recounts Richmond’s unlikely political evolution, she also discovers previously hidden connections to an underground network of British reformers, including future American patriot Thomas Paine. Radical Duke reads like a lively and intellectual detective story, filled with anonymous pamphlets, secret alliances, and descriptions of how these explosive political ideas took root in America and France. It’s a compelling new perspective on the messy, transatlantic origins of modern democracy.
