Classical radicalism

Historical political movement within liberalism

Radicalism (from French radical) was a political movement representing the leftward flank of liberalism between the late 18th and early 20th century. Certain aspects of the movement were precursors to a wide variety of modern-day movements, ranging from laissez-faire to social liberalism, social democracy, civil libertarianism, and modern progressivism. This ideology is commonly referred to as "radicalism" but is sometimes referred to as radical liberalism, or classical radicalism, to distinguish it from radical politics.
