Liberalism 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 and programmes such as freedom of speech, freedom of the press, freedom of religion, free markets, civil rights, democratic societies, secular governments, gender equality, and international cooperation.
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 prevailing social and political norms of hereditary privilege, state religion, absolute monarchy, and the Divine Right of Kings. The 17th-century philosopher 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, while adding that governments must not violate these rights based on the social contract. Liberals opposed traditional conservatism and sought to replace absolutism in government with representative democracy and the rule of law.
