The Enlightenment, spanning the 17th to 18th centuries, promoted reason, individualism, and challenging traditional authority. It encouraged the pursuit of knowledge, scientific progress, religious tolerance, and human rights. Influential figures like Voltaire, Rousseau, and Kant spearheaded this movement, which inspired political and social revolutions, including the American and French Revolutions. The Enlightenment's legacy includes shaping modern democracy, advocating for individual rights, and fostering a more secular worldview.
