Conservatism in the United States is a right-leaning and right-wing tradition of a variety of ideologies that collectively has rivaled the liberal and progressive U.S. political traditions. Since the early 20th century, the American conservative tradition has generally been identified with the Republican Party, as opposed to the predominantly modern social-liberal orientation of its rival, the Democratic Party. Traditional American conservatism is characterized by a belief in individualism, traditionalism, capitalism, republicanism, and limited federal governmental power in relation to U.S. states. However, developments since 2010 have shifted it towards right-wing populist and national-conservative themes, owing in a large part to Trumpism.
