Conservative liberalism, also referred to as right-liberalism, 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 more positive and 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. Ordoliberalism is an influential component of conservative-liberal thought, particularly in its German, British, French, Italian, and American manifestations.
