Liberalism is a political and moral philosophy based on the rights of the individual, liberty, consent of the governed and equality before the law. Liberals espouse various views depending on their understanding of these principles. However, they generally support private property, market economies, individual rights (including civil rights and human rights), liberal democracy, secularism, rule of law, economic and political freedom, freedom of speech, freedom of the press, freedom of assembly, and freedom of religion. Liberalism is frequently cited as the dominant ideology of modern times.

Liberalism became a distinct movement in the Age of Enlightenment, gaining popularity among Western philosophers and economists. Liberalism sought to replace the norms of hereditary privilege, state religion, absolute monarchy, the divine right of kings and traditional conservatism with representative democracy and the rule of law. Liberals also ended mercantilist policies, royal monopolies and other trade barriers, instead promoting free trade and marketization. Philosopher John Locke is often credited with founding liberalism as a distinct tradition based on the social contract, arguing that each man has a natural right to life, liberty and property, and governments must not violate these rights. While the British liberal tradition has emphasized expanding democracy, French liberalism has emphasized rejecting authoritarianism and is linked to nation-building. (Full article...)
