Conservatism in the United States
Historically, the central themes in American conservatism have included respect for American traditions, support of republicanism and the rule of law, Judeo-Christian values, anti-Communism, advocacy of American exceptionalism and a defense of Western civilization from perceived threats posed by moral relativism, multiculturalism, and postmodern ridicule of traditional culture. Liberty is a core value, with a particular emphasis on strengthening the free market, and opposition to high taxes and government or labor union encroachment on the entrepreneur.
In recent decades, historians argue that the conservative tradition has played a major role in American politics and culture since the American Revolution. 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, but during the era of segregation, before 1965, many Southern Democrats were also conservative. Southern Congressmen were a key part of a Conservative Coalition that largely blocked liberal labor legislation in Congress from 1937 to 1963, though they tended to be liberal and vote with the rest of the Democratic Party on other economic issues. Southern Democrats fended off the more conservative Republican Party (GOP) by arguing that only they could defend segregation because the Republican Party nationally was committed to integration. That argument collapsed when Congress banned segregation in 1964. This provided an opportunity for Republicans to appeal to conservative Southerners on the basis that the GOP was the more conservative party on a wide range of social and economic issues, as well as being hawkish on foreign policy when the antiwar forces gained strength in the Democratic party. Southern white conservatives moved from the Democratic Party to the GOP at the presidential level in the 1960s, and at the state and local level after 1990.
