The Republican Party, also commonly called the GOP (for “Grand Old Party”), is one of the two major contemporary political parties in the United States, the other being the Democratic Party. Founded by anti-slavery activists in 1854, it dominated politics nationally for most of the period from 1860 to 1932. There have been 19 Republican presidents, the first being Abraham Lincoln, serving from 1861 to 1865, and the most recent being Donald J. Trump, serving from 2017 to present.
Currently the party’s platform is generally based upon American conservatism, in contrast to the Democratic Party, who endorse more liberal policies. American conservatism of the Republican Party is not wholly based upon rejection of the political ideology of liberalism, as many principles of American conservatism are based upon classical liberalism. Rather, the Republican Party’s conservatism is largely based upon its support of classical principles against the modern liberalism of the Democratic Party that is considered American liberalism in contemporary American political discourse.
