Libertarian conservatism, also referred to as conservative libertarianism and, more rarely, conservatarianism, is a libertarian political and social philosophy that combines conservatism and libertarianism, representing the libertarian wing of conservatism and vice versa.
Libertarian conservatism advocates the greatest possible economic liberty and the least possible government regulation of social life (described as "small government"), mirroring laissez-faire classical liberalism, but harnesses this to a belief in a more socially conservative philosophy emphasizing authority, morality, and duty. Primarily an American ideology, libertarian conservatism prioritizes liberty, promoting free expression, freedom of choice and free-market capitalism to achieve conservative ends while rejecting liberal social engineering.
