Conservative Liberalism is a variant of Liberalism representing the right-wing of the Liberal movement, and combines liberal values and policies with conservative stances. Unlike Liberal Conservatives, however, who tend to be more committed to authority, tradition and established religion, Conservative Liberals are supporters of the separation between church and state. It also differs from Libertarianism in that it is far less radical in its economic program, and in its support for an active defense policy and military interventions.
Economic Liberalism is the theory of economics in Classical Liberalism, developed during the Enlightenment, particularly by Adam Smith, which advocates minimal interference by government in the economy. Libertarianism, Neoliberalism and some schools of Conservatism, particularly Liberal Conservatism are often referred to as Economic Liberalism.
Neoliberalism refers to a program of reducing trade barriers and internal market restrictions, while using government power to enforce opening of foreign markets. In some ways it is a modern attempt, championed by Conservatives like Ronald Reagan and Margaret Thatcher since the 1970's, to revert to a more pure Classical Liberalism.
American Liberalism is largely a combination of social liberalism, social progressivism, and mixed economy philosophy. It is distinguished from Classic Liberalism (see above) and Libertarianism, which also claim freedom as their primary goal, in its insistance upon the inclusion of positive rights (such as education, health care and other services and goods believed to be required for human development and self-actualization) and in a broader definition of equality.
National Liberalism is a variant of Liberalism commonly found in several European countries in the 19th and 20th Century, which combines nationalism with policies mainly derived from Economic Liberalism (see above).
Ordoliberalism is a mid-20th Century school of Liberalism, developed mainly in Germany, emphasizing the need for the state to ensure that the free market produces results close to its theoretical potential.
Paleoliberalism is a term that has at least a few distinct, though largely ambigious, meanings, including extreme Liberalism, and very socialist or socially libertarian Liberalism, and opposed to Neoliberalism (see above).
Cultural Liberalism is a liberal view of society that stresses the freedom of individuals from cultural norms.
