Through Right-wing politics, Abraham Lincoln and American Civil War

The Republican Party was founded 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, and 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 two of the parties voting blocs' (African Americans and White Southerners). 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 tariffs while opposing free trade and labor unions.

During the 20th and early 21st centuries, the Republican Party has cooperated internationally with conservative parties. Since the 2020s it has aligned with global far-right parties, Hispanic and Latino conservatives, black conservatives, and Asian American and Pacific Islander conservatives, while ethno-nationalist beliefs have become influential within the party, including support for remigration.

History

1850s to 1930s

In 1854, the Republican Party began as an anti-slavery party to combat the expansion of slavery into western territories after the passing of the Kansas–Nebraska Act by the Democrats under Stephan Douglas. The party was formed in the Northern and Border states, but not the South. It rapidly gained support in the North, drawing in former Whigs and Free Soil Democrats. Under the Presidency of Abraham Lincoln it led the successful war effort against the Confederacy.

By 1865 it encompassed northern Protestants, factory workers, professionals, businessmen, prosperous farmers, and also black former slaves. It also included a minority of white Southerners who had opposed the Confederacy—men ridiculed by Democrats as "Scalawags". The great majority of white southerners were Democrats, as were the great majority of Irish Catholics and German Catholics. While both parties adopted pro-business policies in the 19th century, the early GOP was distinguished by its support for the national banking system, the gold standard, railroads, and high tariffs.

The Republican Party largely dominated the national political scene until 1932. However it split in 1912, as former president Theodore Roosevelt formed the liberal Progressive Party to oppose the conservatives under William Howard Taft. The split allowed Democrats under Woodrow Wilson to win in 1912. The GOP lost its congressional majorities during the Great Depression (1929–1940). Under Franklin D. Roosevelt and Harry S Truman, the Democrats formed a winning New Deal coalition that was dominant from 1932 through 1952.

Shift rightward

After the Civil Rights Act of 1964, the Voting Rights Act of 1965, and the Southern strategy, the party's core base shifted with the Southern states becoming more reliably Republican in presidential politics and the Northeastern states becoming more reliably Democratic. White voters increasingly identified with the Republican Party after the 1960s. Following the Supreme Court's 1973 decision in Roe v. Wade, the Republican Party opposed abortion in its party platform and grew its support among evangelicals. The Republican Party won five of the six presidential elections from 1968 to 1988. Two-term President Ronald Reagan, who held office from 1981 to 1989, was a transformative party leader. His conservative policies called for reduced social government spending and regulation, increased military spending, lower taxes, and a strong anti-Soviet foreign policy. Reagan's influence upon the party persisted into the early 21st century.

Since the 1990s, the party's support has chiefly come from the South, the Great Plains, the Mountain States, and rural areas in the North.

Trump era

In the 2016 presidential election, Republican nominee Donald Trump defeated Democratic nominee Hillary Clinton. The result was unexpected; polls leading up to the election showed Clinton leading the race. Trump's victory was fueled by narrow victories in three states—Michigan, Pennsylvania, and Wisconsin—that had been part of the Democratic blue wall for decades. It was attributed to strong support amongst working-class white voters, who felt dismissed and disrespected by the political establishment. Trump became popular with them by abandoning Republican establishment orthodoxy in favor of a broader nationalist message. His election accelerated the Republican Party's shift towards right-wing populism and resulted in decreasing influence among its conservative factions.

After the 2016 elections, Republicans maintained their majority in the Senate, the House, and governorships, and wielded newly acquired executive power with Trump's election. The Republican Party controlled 69 of 99 state legislative chambers in 2017, the most it had held in history. The Party also held 33 governorships, the most it had held since 1922. The party had total control of government in 25 states, the most since 1952. The opposing Democratic Party held full control of only five states in 2017. In the 2018 elections, Republicans lost control of the House, but strengthened their hold on the Senate.

Over the course of his presidency, Trump appointed three justices to the Supreme Court. Trump lost the 2020 presidential election to Joe Biden but refused to concede the race, claiming widespread electoral fraud and attempting to overturn the results. On January 6, 2021, the United States Capitol was attacked by Trump supporters following a rally at which Trump spoke. After the attack, the House impeached Trump for a second time on the charge of incitement of insurrection, making him the only federal officeholder to be impeached twice; however, he was not removed from office. The Senate acquitted him in February 2021, after he had already left office.

Following the 2020 election, election denial became increasingly mainstream in the party, with the majority of Republican candidates in 2022 being election deniers. The party also made efforts to restrict voting based on false claims of fraud. Furthermore, the party began to systematically downplay, deny, or reinterpret controversial actions from Trump's first term, particularly the Capitol attack, regarding which the party has circulated revisionist narratives, some of which are also being presented as official accounts during Trump's second term.

By the early 2020s, the Republican Party had largely shifted towards illiberalism, with a 2020 study conducted by the V-Dem Institute concluding that it was more ideologically extreme than France's National Rally and similar in its views, rhetoric, actions and practices to authoritarian or far-right parties such as Law and Justice in Poland, Fidesz in Hungary, Justice and Development in Turkey, Bharatiya Janata Party in India, and Alternative for Germany. The United States has experienced substantial democratic backsliding under the two presidencies of Donald Trump, with a majority of political scientists and several democracy indices classifying the country as either having transitioned or being in a phase of transition from a liberal democracy to an illiberal democracy or hybrid regime since 2016.

Trump easily won the nomination to be the party's candidate again in 2024, marking the third straight election of him being the GOP nominee. Trump achieved victory against Vice President Kamala Harris. He won both the electoral college and a plurality of the popular vote, becoming the first Republican to do so since George W. Bush in 2004, and improving his vote share among working class voters, particularly among young men, those without college degrees, and Hispanic voters.

Current status

As of 2026, the GOP holds the presidency, and majorities in both the U.S. House of Representatives and U.S. Senate, giving them a federal government trifecta. It also holds 26 state governorships, 28 state legislatures, and 23 state government trifectas. Six of the nine current U.S. Supreme Court justices were appointed by Republican presidents. There have been 19 Republicans who have served as president, the most from any one political party; the most recent being current president Donald Trump, who became the 47th president on January 20, 2025. Trump also served as the 45th president from 2017 to 2021.

During Trump's second term, the GOP has been partially divided on a number of key policies, including tariffs and support for Ukraine in the Russo-Ukrainian war.
