Classical liberalism was a political ideology that developed in the nineteenth century in Western Europe, and the Americas. It was committed to the ideal of limited government and liberty of individuals including freedom of religion, speech, press, assembly, and free markets. It drew on the economics of Adam Smith, a psychological understanding of individual liberty, natural law and utilitarianism, and a belief in progress. Classical liberals established political parties that were called “Liberal”, although in the United States classical liberalism came to dominate both existing major political parties. Notable individuals who have contributed to classical liberalism include Jean-Baptiste Say, Thomas Malthus, and David Ricardo. There was a revival of interest in classical liberalism in the twentieth century led by Ludwig von Mises, Friedrich Hayek and other economists.The phrase classical liberalism is also sometimes used to refer to all forms of liberalism before the twentieth century. And some conservatives and libertarians use the term classical liberalism to describe their belief in the primacy of economic freedom and minimal government. It is not always clear which meaning is intended.
