What economic ideas were popular during enlightenment?

During the Enlightenment, several key economic ideas emerged, most notably the concept of free markets and the principles of capitalism. Thinkers like Adam Smith advocated for laissez-faire economics, arguing that individuals pursuing their self-interest would lead to greater overall prosperity, encapsulated in his famous notion of the "invisible hand." Additionally, ideas about rational economic behavior and the importance of competition were developed, challenging mercantilist views that prioritized state control and protectionism. These Enlightenment ideas laid the groundwork for modern economic theory and practices.
