While the concept of limited government dates back to the Magna Carta, the idea was further developed by Enlightenment thinkers in the seventeenth and eighteenth centuries. The idea that government power requires the consent of the governed originates from John Locke. The concept of separating the government into three branches is attributed to Baron de Montesquieu, and the idea that the government should avoid intervening in commerce is frequently attributed to Adam Smith. Many of these ideas were later integrated into the American and French revolutions.
