Classical liberalism is a political tradition and a branch of liberalism that advocates free market and laissez-faire economics and civil liberties under the rule of law, with special emphasis on individual autonomy, limited government, economic freedom, political freedom and freedom of speech. Classical liberalism, contrary to liberal branches like social liberalism, looks more negatively on social policies, taxation and the state involvement in the lives of individuals, and it advocates deregulation.

Adam Smith was a Scottish economist and philosopher who was a pioneer in the thinking of political economy and key figure during the Scottish Enlightenment. Seen by some as "The Father of Economics" or "The Father of Capitalism", he wrote two classic works, The Theory of Moral Sentiments (1759) and An Inquiry into the Nature and Causes of the Wealth of Nations (1776). The latter, often abbreviated as The Wealth of Nations, is considered his magnum opus and the first modern work that treats economics as a comprehensive system and as an academic discipline. Smith refuses to explain the distribution of wealth and power in terms of God's will and instead appeals to natural, political, social, economic, legal, environmental and technological factors and the interactions among them. Among other economic theories, the work introduced Smith's idea of absolute advantage.
