Book excerpt: Reviews over two dozen coercion-based practices, including human sacrifice, genocide, war, terrorism, revolution, political murder, riots, homicide, imprisonment, capital punishment, torture, religious persecution, slavery, debt bondage, and taxation. Examples and data are drawn from all over the world, including ancient Rome, medieval Japan, early modern England, revolutionary Russia, and four centuries of American history. Payne concludes that the long-run tendency in societies is for the use of force to decline.
