Republican Party (United States)

The Republican Party, also known as the Grand Old Party (GOP), is a right-wing populist and neo-nationalist political party in the United States, sitting on the right-wing to far-right of the political spectrum. Founded in 1854, it emerged as the main rival of the Democratic Party in the 1850s, and the two parties have dominated American politics since then.

The Republican Party was founded in 1854 by anti-slavery activists who opposed the Kansas–Nebraska Act and the expansion of slavery into American territories. It rapidly gained support in the North, drawing in former Whigs, Free Soilers, and former Know Nothings. Abraham Lincoln's election in 1860 as president led to the secession of Southern states and the outbreak of the American Civil War. Under Lincoln and a Republican-controlled Congress, the party led efforts to preserve the Union, defeat the Confederacy, and abolish slavery. During the Reconstruction era, Republicans sought to extend civil rights protections to freedmen, but by the late 1870s, the party shifted its focus toward business interests and industrial expansion. In the late 19th and early 20th centuries, it dominated national politics, promoting protective tariffs, infrastructure development, and laissez-faire economic policies, while navigating internal divisions between progressive and conservative factions. The party's support declined during the Great Depression, as the New Deal coalition reshaped American politics. Republicans returned to national power with the 1952 election of Dwight D. Eisenhower, whose moderate conservatism reflected a pragmatic acceptance of many New Deal-era programs.

Following the civil rights era, the Republican Party's use of the Southern strategy appealed to many white voters disaffected by Democratic support for civil rights, and de facto flipping the two parties' stances. The 1980 election of Ronald Reagan as president realigned national politics, consolidating a coalition of free market advocates, social conservatives and foreign policy hawks under the Republican banner. Since 2009, a shift toward right-wing populism culminated in the 2016 election of Donald Trump as president, whose leadership style and political agenda—often referred to as Trumpism—reshaped the party's identity and political platform.

The present-day Republican Party is primarily right-wing populist and neo-nationalist with smaller conservative, Christian right, and libertarian factions, all of which have greatly diminished in influence since 2016. Its ideology has since largely shifted towards illiberalism, favoring strong presidential power and a statist government to enforce conservative cultural values. This includes broad opposition to abortion, LGBT rights, immigration, and gun control. On economic policy, it supports mercantilism while opposing labor unions. During the 20th and early 21st centuries, it cooperated internationally with conservative parties. Since the 2020s it has aligned with global far-right parties, and white nationalist beliefs have become influential within the party, including support for remigration.
