Alexis de Tocqueville, a young aristocratic French lawyer, came to the United States in 1831 to study its penitentiary systems. His nine-month visit and subsequent reading and reflection resulted in Democracy in America (1835–40), a landmark masterpiece of political observation and analysis. Tocqueville vividly describes the unprecedented social equality he found in America and explores its implications for European society in the emerging modern era. His book provides enduring insight into the political consequences of widespread property ownership, the potential dangers to liberty inherent in majority rule, the importance of civil institutions in an individualistic culture dominated by the pursuit of material self-interest, and the vital role of religion in American life, while prophetically probing the deep differences between the free and slave states.
