Republican Party (United States)
The Republican Party, commonly referred to as the GOP (abbreviation for Grand Old Party), is one of the two major contemporary political parties in the United States, the other being its historic rival, the Democratic Party.
Founded by anti-slavery activists, modernists, ex-Whigs, and ex-Free Soilers in 1854, the Republicans dominated politics nationally and in the majority of northern States for most of the period between 1860 and 1932. There have been 18 Republican presidents, the first being Abraham Lincoln, who served from 1861 until his assassination in 1865, and the most recent being George W. Bush, who served from 2001 to 2009. The most recent Republican presidential nominee is former Massachusetts Governor Mitt Romney, who lost in 2012 to Democratic incumbent Barack Obama.
Although it is named after republicanism, that concept is no longer widely used. Instead republican ideals have been incorporated into the concept of conservatism, which serves as the ideological core of the party. This conservatism contrasts with the modern liberalism of the Democrats. The Republican Party's conservatism involves support for free market capitalism, free enterprise, business, a strong national defense, deregulation, restrictions on labor unions, social-conservative policies (particularly opposition to abortion), and traditional values, usually with a Christian foundation. The party is deeply split on the issue of how to deal with illegal immigration.
