The Encyclopédistes were a group of 18th century writers in France who compiled the Encyclopédie (Encyclopedia) edited by Denis Diderot and Jean le Rond d'Alembert. Like Pierre Bayle (1647-1706), who created the Historical and Critical Dictionary, the Encyclopédistes were part of the intellectual group known as the philosophes. They promoted the advancement of science and secular thought, and supported the tolerance, rationality and open-mindedness of the Enlightenment.
