Saint-Simonianism was a French political and social movement of the first half of the 19th century, inspired by the ideas of Claude Henri de Rouvroy, comte de Saint-Simon (1760–1825).
Saint-Simon's ideas, expressed largely through a succession of journals such as l'Industrie (1816), La politique (1818) and L'Organisateur (1819–20) centered on a perception that growth in industrialization and scientific discovery would have profound changes on society. He believed, nonetheless, that society would restructure itself by abandoning traditional ideas of temporal and spiritual power, an evolution that would lead, inevitably, to a productive society based on, and benefiting from, a " ... union of men engaged in useful work", the basis of "true equality".
