European politics, philosophy, science and communications were radically reoriented during the course of the “long 18th century” (1685-1815) as part of a movement referred to by its participants as the Age of Reason, or simply the Enlightenment. Enlightenment thinkers in Britain, in France and throughout Europe questioned traditional authority and embraced the notion that humanity could be improved through rational change. The Enlightenment produced numerous books, essays, inventions, scientific discoveries, laws, wars and revolutions. The American and French Revolutions were directly inspired by Enlightenment ideals and respectively marked the peak of its influence and the beginning of its decline. The Enlightenment ultimately gave way to 19th-century Romanticism.
