By giving rise to new ideologies that in time transformed the political structure of much of the world, the American and French Revolutions stand as two of the most important political events in global history. The American establishment of a Republican government, and the gradual expansion of democracy that ensued, altered traditional political and social thought, thus shaping the later French Revolution and creating the core ethic of later American political values. The Enlightenment ideals of the French Revolution, as later spread by the armies of Napoleon, dissolved most traditional European notions of political authority. This encyclopedia offers current, detailed information on the people, events, movements, and ideas that defined the revolutions in France and America, as well as in other parts of the world during the late eighteenth-century Age of Revolutions.
