or GOP (Grand Old Party)
One of two major U.S. political parties.
It was formed in 1854 by former members of the Whig , Democratic , and Free Soil parties who chose the party's name to recall the Jeffersonian Republicans' concern with the national interest above sectional interests and states' rights . The new party opposed slavery and its extension into the territories, as provided by the Kansas-Nebraska Act . Its first presidential candidate, John C. Frémont , won 11 states in 1856; its second, Abraham Lincoln , won the 1860 election by carrying 18 states. Its association with the Union victory in the American Civil War allowed it a long period of dominance nationally, though it was uncompetitive in the South for more than a century after the war. Republican candidates won 14 of 18 presidential elections between 1860 and 1932, through support from an alliance of Northern and Midwestern farmers and big-business interests. In 1912 the party split between a progressive wing led by Theodore Roosevelt and a conservative wing led by Pres. William Howard Taft ; the rift enabled the Democratic candidate, Woodrow Wilson, to win that year's election. The Republican Party's inability to counter the impact of the Great Depression led to its ouster from power in 1933; in 1953 the presidency of Dwight D. Eisenhower brought a moderate wing of the party to prominence. The party's platform remained conservative, emphasizing anticommunism, reduced government regulation of the economy, and lower taxes; many members also opposed civil rights legislation. In the 1950s the GOP gained new support from middle-class suburbanites and white Southerners disturbed by the integrationist policies of the national Democratic Party. Richard Nixon , who narrowly lost the 1960 presidential race, won narrowly in 1968 and by a landslide in 1972, but he was forced to resign in 1974 as a result of the Watergate scandal . Ronald Reagan , who had assumed the leadership of the conservative wing of the Republican Party after Barry Goldwater 's defeat in the presidential election of 1964, won the presidency in 1980 and 1984; he introduced deep tax cuts and launched a massive buildup of U.S. military forces. Reagan's vice president, George Bush, was elected in 1988 and enjoyed enormous popularity after success in the First Persian Gulf War, but an anemic economy led to his defeat in 1992 by Democrat Bill Clinton . The defeat was offset in 1994, when the Republicans regained control of the House of Representatives for the first time in 40 years. In 2000 George W. Bush narrowly won the presidency in one of the closest and most controversial elections in U.S. history. In 2004 he won reelection. The party continues to emphasize tax cuts, traditional social values, and strong national defense.
