Conservative liberalism, also referred to as right-liberalism,^{[page needed]} is a variant of liberalism combining liberal values and policies with conservative stances, or simply representing the right wing of the liberal movement. In the case of modern conservative liberalism, scholars sometimes see it as a less radical variant of classical liberalism; it is also referred to as an individual tradition that distinguishes it from classical liberalism and social liberalism. Conservative liberal parties tend to combine economically liberal policies with more traditional stances and personal beliefs on social and ethical issues.^[specify] Ordoliberalism is an influential component of conservative-liberal thought, particularly in its German, British, Canadian, French, Italian, and American manifestations.

In general, liberal conservatism and conservative liberalism have different philosophical roots. Historically, liberal conservatism refers mainly to the case where conservatives embrace the elements of classical liberalism, and conservative liberalism refers to classical liberals who support a laissez-faire economy as well as socially conservative principles. Since conservatives gradually accepted classical liberal institutions, there is very little to distinguish liberal conservatives from conservative liberals. Neoconservatism has also been identified as an ideological relative or twin to conservative liberalism, and some similarities exist also between conservative liberalism and national liberalism.

Conservative liberalism emerged in late 18th-century France and the United Kingdom, when the moderate bourgeoisie supported the monarchy within the liberal camp. Representatively, Doctrinaires, which existed during the Bourbon Restoration was a representative conservative-liberal party. Radicalism, the leftward flank of liberalism during the late 18th and early 19th centuries that is referred to as classical radicalism, emerged as an opposition against the moderateness of these conservative liberals. Whiggism, or Whig liberalism, in the United Kingdom also forms early conservative liberalism and is distinguished from the Radicals (radical liberalism).

According to Robert Kraynak, a professor at Colgate University, rather than "following progressive liberalism (i.e. social liberalism), conservative liberals draw upon pre-modern sources, such as classical philosophy (with its ideas of virtue, the common good, and natural rights), Christianity (with its ideas of natural law, the social nature of man, and original sin), and ancient institutions (such as common law, corporate bodies, and social hierarchies). This gives their liberalism a conservative foundation. It means following Socrates, Plato, Aristotle, St. Augustine, St. Thomas Aquinas, and Edmund Burke rather than Locke or Kant; it usually includes a deep sympathy for the politics of the Greek polis, the Roman Republic, and Christian monarchies. But, as realists, conservative liberals acknowledge that classical and medieval politics cannot be restored in the modern world. And, as moralists, they see that the modern experiment in liberty and self-government has the positive effect of enhancing human dignity as well as providing an opening (even in the midst of mass culture) for transcendent longings for eternity. At its practical best, conservative liberalism promotes ordered liberty under God and establishes constitutional safeguards against tyranny. It shows that a regime of liberty based on traditional morality and classical-Christian culture is an achievement we can be proud of, rather than merely defensive about, as trustees of Western civilization."

In the European context, conservative liberalism should not be confused with liberal conservatism, which is a variant of conservatism combining conservative views with liberal policies in regards to the economy, social and ethical issues. The roots of conservative liberalism are to be found at the beginning of the history of liberalism. Until the two world wars, the political class in most European countries from Germany to Italy was formed by conservative liberals. The events such as World War I occurring after 1917 brought the more radical version of classical liberalism to a more conservative (i.e. more moderate) type of liberalism. Conservative liberal parties have tended to develop in those European countries where there was no strong secular conservative party and where the separation of church and state was less of an issue. In those countries, where the conservative parties were Christian democratic, this conservative brand of liberalism developed.

Conservative liberalism is generally a liberal ideology that contrasts with social liberalism. Conservative liberalism, along with social liberalism and classical liberalism, is mentioned as the main liberal ideology of European politics. While there are conservative liberals who are located on the right-wing political position, conservative liberalism is often used to describe liberalism close to the political centre to the centre-right of the political spectrum.

Social liberalism is a combination of economic Keynesianism and cultural liberalism. Classical liberalism is economic liberalism that partially embraces cultural liberalism. Conservative liberalism is an ideology that highlights the conservative aspect of liberalism, so it can appear in a somewhat different form depending on the local reality. Conservative liberalism refers to ideologies that show relatively conservative tendencies within the liberal camp, so it has some relative meaning. In the United States, conservative liberals mean de facto classical liberals; in Europe, Christian democrats and ordoliberals can also be included. Christian democracy is a mainstream European conservative ideology, so there are cases where it supports free markets, such as Röpke.

Alexis de Tocqueville and Adolphe Thiers were representative French conservative liberals. They were classified as centre-left liberals (progressive-Orléanists) during the July Monarchy alone; after the French Revolution of 1848, the now French Second Republic entered and they were relegated to conservative liberals.^{[citation needed]}
