The Book That Inspired Revolutions

Rousseau's The Social Contract opens with one of philosophy's most famous lines: "Man is born free, and everywhere he is in chains." It argues that legitimate political authority comes not from divine right or force but from a social contract among free citizens. Its ideas directly inspired both the French and American Revolutions.

Published in 1762, The Social Contract challenged the entire basis of political authority in Europe. Rousseau argued that sovereignty belongs to the people, not to kings, and that any government that fails to serve the general will has lost its legitimacy. These ideas were intellectual dynamite in the age of absolute monarchy.
