Abstract
In the closing years of the eighteenth century, a great intellectual and moral challenge to European empire was launched by many of the most innovative thinkers of the day, including Kant, Adam Smith, Bentham, Burke, Diderot, and Condorcet. They drew on a strikingly wide range of ideas to argue against empire: among others, the rights of man and the imperative of popular self‐determination, the economic wisdom of free trade and foolishness of conquest, the corruption of natural man by a degenerate civilization, the hypocrisy required for self‐governing republics to rule despotically over powerless subjects, and the impossibility of sustaining freedom at home while practicing despotism abroad.
