American Conservatism is a broad system of political beliefs in the United States that is characterized by respect for American traditions, support for Judeo-Christian values, economic liberalism, anti-communism, advocacy of American exceptionalism, and a defense of Western culture from perceived threats posed by "creeping socialism", moral relativism, multiculturalism, and liberal internationalism. Liberty is a core value, with a particular emphasis on strengthening the free market, limiting the size and scope of government, and opposition to high taxes and government or labor union encroachment on the entrepreneur. American conservatives consider individual liberty, within the bounds of conformity to American values, as the fundamental trait of democracy, which contrasts with modern American liberals, who generally place a greater value on equality and social justice.
American conservatism originated from classical liberalism of 18th and 19th centuries, which advocates civil liberties and political freedom with representative democracy under the rule of law and emphasizes economic freedom.
Historians argue that the conservative tradition has played a major role in American politics and culture since the 1790s. However they have stressed that an organized conservative movement has played a key role in politics only since the 1950s. The recent movement is based in the Republican Party, though some Democrats were also important figures early in the movement's history.
