American nationalism in the context of Naturalization Act of 1790

Paleoconservatism is a political philosophy and a strain of conservatism in the United States stressing American nationalism, Christian ethics, regionalism, traditionalist conservatism, and non-interventionism. Paleoconservatism's concerns overlap with those of the Old Right that opposed the New Deal in the 1930s and 1940s as well as with paleolibertarianism.

The terms neoconservative and paleoconservative were coined by Paul Gottfried in the 1980s, originally relating to the divide in American conservatism over the Vietnam War. Those supporting the war became known as the neoconservatives (interventionists), as they made a decisive split from traditional conservatism (nationalist isolationism), which then became known as paleoconservatism. Paleoconservatives press for restrictions on immigration, a rollback of multicultural programs and large-scale demographic change, the decentralization of federal policy, the restoration of controls upon free trade, a greater emphasis upon economic nationalism, and non-intervention in the politics of foreign nations.

The Third Party System was a period in the history of political parties in the United States from the 1850s until the 1890s, which featured profound developments in issues of American nationalism, modernization, and race. This period was marked by the American Civil War (1861–1865), the Emancipation Proclamation and the end of slavery in the United States, followed by the Reconstruction era and the Gilded Age.

It was dominated by the new Republican Party, which claimed success in saving the Union, abolishing slavery and enfranchising the freedmen, while adopting many Whig-style modernization programs such as national banks, railroads, high tariffs, homesteads, social spending (such as on greater Civil War veteran pension funding), and aid to land grant colleges. While most elections from 1876 through 1892 were extremely close, the opposition Democrats won only the 1884 and 1892 presidential elections (the Democrats also won the popular vote in the 1876 and 1888 presidential elections, but lost the electoral college vote), though from 1875 to 1895 the party usually controlled the United States House of Representatives and controlled the United States Senate from 1879 to 1881 and 1893 to 1895. Indeed, scholarly work and electoral evidence emphasizes that after the 1876 election the South's former slave centers, which before the emancipation of Republican-voting African Americans was electorally dominated by wealthy slave owners who made up the southern base of Whigs, Know Nothings and Constitutional Unionists, began realigning into the Democratic Party due to the end of the now unpopular Reconstruction efforts; this new electoral base for the Democrats would finish realigning around 1904.

John Caldwell Calhoun (/kælˈhuːn/; March 18, 1782 – March 31, 1850) was an American statesman and political theorist who served as the seventh vice president of the United States from 1825 to 1832. Calhoun began his political career as a nationalist, modernizer and proponent of a strong federal government and protective tariffs. In the late 1820s, his views shifted, and he became a leading proponent of states' rights, limited government, nullification, and opposition to high tariffs, and distinguished himself as an outspoken defender of American slavery. Calhoun saw Northern acceptance of those policies as a condition of the South remaining in the Union. His beliefs heavily influenced the South's secession from the Union in 1860 and 1861. Calhoun was the first of two vice presidents to resign from the position, the second being Spiro Agnew, who resigned in 1973.

Born in South Carolina, Calhoun began his political career with election to the House of Representatives in 1810. As a prominent leader of the war hawk faction, he strongly supported the War of 1812. Calhoun served as Secretary of War under President James Monroe and, in that position, reorganized and modernized the War Department. He was a candidate for the presidency in the 1824 election. After failing to gain support, Calhoun agreed to be a candidate for vice president. The Electoral College elected him vice president by an overwhelming majority. He served under John Quincy Adams and continued under Andrew Jackson, who defeated Adams in the election of 1828, making Calhoun the most recent U.S. vice president to serve under two different presidents.

Donald Trump, the 45th president of the United States (2017–2021) ran a successful campaign for the 2024 U.S. presidential election. He formally announced his campaign on November 15, 2022, initially battling for the Republican Party's nomination. While many candidates challenged the former president for the nomination, they did not manage to amass enough support, leading Trump to a landslide victory in the 2024 Iowa caucuses. On March 12, 2024, he became the Republican Party's presumptive nominee. Trump was officially nominated on July 15 at the Republican National Convention, where he chose JD Vance, the junior U.S. senator from Ohio, as his vice presidential running mate. On November 5, Trump and Vance were elected president and vice president of the United States, winning all seven swing states as well as the popular vote with a plurality.

Trump's agenda was branded as populist and nationalist. It pledged sweeping tax cuts, a protectionist trade policy, greater federal oversight over education, more extensive use of fossil fuels, an "America First" foreign policy, an expansion of presidential authority, a reduction of federal regulations, mass deportation of illegal immigrants, stricter law enforcement, an end to diversity, equity, and inclusion programs, and a rollback of transgender rights. While the campaign's official platform was Agenda 47, it was closely connected to The Heritage Foundation's Project 2025, a playbook recommending an authoritarian, rigidly conservative state.
