Conservatism in the United States has played an important role in American politics since the 1950s.
Historian Gregory Schneider identifies several constants in American conservatism: respect for tradition, support of
republicanism, preservation of "the rule of law and the Christian religion", and a defense of "Western civilization from the challenges of modernist culture and totalitarian governments."
The history of American conservatism has been marked by tensions and competing ideologies. Economic conservatives and libertarians favor
small government, low taxes, limited regulation, and free enterprise. Social conservatives see traditional social values as threatened by secularism, so they support
school prayer and
oppose abortion and
homosexuality.
Neoconservatives want to expand American ideals throughout the world and show a strong support for Israel.
Paleoconservatives, in opposition to multiculturalism, press for restrictions on immigration.
Most conservatives prefer Republicans over Democrats, and most factions favor a strong foreign policy, a strong military, and strong support for Israel. The conservative movement of the 1950s attempted to bring together these divergent strands, stressing the need for unity to prevent the spread of "Godless Communism".
