Liberalism (from the Latin liberalis) is a political philosophy or worldview founded on ideas of liberty and equality. Liberals espouse a wide array of views depending on their understanding of these principles, but generally they support ideas such as free and fair elections, civil rights, freedom of the press, freedom of religion, free trade, and private property.
Liberalism first became a distinct political movement during the Age of Enlightenment, when it became popular among philosophers and economists in the Western world. Liberalism rejected the notions, common at the time, of hereditary privilege, state religion, absolute monarchy, and the Divine Right of Kings. The early liberal thinker John Locke is often credited with founding liberalism as a distinct philosophical tradition. Locke argued that each man has a natural right to life, liberty and property and according to the social contract, governments must not violate these rights. Liberals opposed traditional conservatism and sought to replace absolutism in government with democracy and/or republicanism and the rule of law.
