Free Soil Party in the context of "Compromise of 1850"

The Republican Party, also known as the Grand Old Party (GOP), is a conservative and right-wing political party in the United States. 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 opposing the Kansas–Nebraska Act and the expansion of slavery into U.S. territories. It rapidly gained support in the North, drawing in former Whigs and Free Soilers. Abraham Lincoln's election in 1860 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.

Presidential elections were held in the United States on November 7, 1848. Held in the aftermath of the Mexican–American War, General Zachary Taylor of the Whig Party defeated Senator Lewis Cass of the Democratic Party.

Despite Taylor's unclear political affiliations and beliefs, and the Whig opposition to the Mexican–American War, the 1848 Whig National Convention nominated the popular general over party stalwarts such as Henry Clay and Daniel Webster. For vice president, the Whigs nominated Millard Fillmore, a New York Whig known for his moderate views on slavery. Incumbent President James K. Polk, a Democrat, honored his promise not to seek re-election, leaving his party's nomination open. The 1848 Democratic National Convention nominated Senator Lewis Cass of Michigan after former President Martin Van Buren withdrew his bid for a second term over a platform dispute. Van Buren broke from his party to lead the ticket of the Free Soil Party, which opposed the extension of slavery into the territories.

The Republican Party, also known as the Grand Old Party (GOP), is one of the two major political parties in the United States. It is the second-oldest extant political party in the United States after its main political rival, the Democratic Party. In 1854, the Republican Party emerged to combat the expansion of slavery into western territories after the passing of the Kansas–Nebraska Act. The early Republican Party consisted of northern Protestants, factory workers, professionals, businessmen, prosperous farmers, and after the Civil War also of black former juivu. The party had very little support from white Southerners at the time, who predominantly backed the Democratic Party in the Solid South, and from Irish and German Catholics, who made up a major Democratic voting bloc. 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 party opposed the expansion of slavery before 1861 and led the fight to dismantle the Confederate States of America (1861–1865). While the Republican Party had almost no presence in the Southern United States at its inception, it was very successful in the Northern United States, where by 1858 it had enlisted former Whigs and former Free Soil Democrats to form majorities in nearly every Northern state.

With the election of its first president, Abraham Lincoln, in 1860, the party's success in guiding the Union to victory in the Civil War, and the party's role in the abolition of slavery, the Republican Party largely dominated the national political scene until 1932. In 1912, former Republican president Theodore Roosevelt formed the Progressive Party after being rejected by the GOP and ran unsuccessfully as a third-party presidential candidate calling for social reforms. The GOP lost its congressional majorities during the Great Depression (1929–1940); under President Franklin D. Roosevelt, the Democrats formed a winning New Deal coalition that was dominant from 1932 through 1964.

The Second Party System was the political party system operating in the United States from about 1828 to early 1854, after the First Party System ended. The system was characterized by rapidly rising levels of voter interest, beginning in 1828, as demonstrated by Election Day turnouts, rallies, partisan newspapers, and high degrees of personal loyalty to parties.

Two major parties dominated the political landscape: the Democratic Party, led by Andrew Jackson, and the Whig Party, assembled by Henry Clay from the National Republicans and from other opponents of Jackson. Minor parties included the Anti-Masonic Party, an important innovator from 1827 to 1834; the abolitionist Liberty Party in 1840; and the anti-slavery expansion Free Soil Party in 1848 and 1852. The Second Party System reflected and shaped the political, social, economic and cultural currents of the Jacksonian Era, until succeeded by the Third Party System.

Martin Van Buren (/væn ˈbjʊərən/ van BYOO-rən; Dutch: Maarten van Buren [ˈmaːrtə(ɱ) vɑm ˈbyːrə(n)] ; December 5, 1782 – July 24, 1862) was the eighth president of the United States, serving from 1837 to 1841. A primary founder of the Democratic Party, Van Buren held a number of prominent offices. He served as New York's attorney general and U.S. senator, then briefly as the ninth governor of New York. After joining Andrew Jackson's administration, he served as the tenth United States secretary of state, minister to the United Kingdom, and ultimately, as the eighth vice president from 1833 to 1837, after being elected on Jackson's ticket in 1832. Van Buren won the presidency in 1836 against divided Whig opponents. He lost re-election in 1840, and failed to win the Democratic nomination in 1844. Later in his life, Van Buren re-emerged as an elder statesman and an anti-slavery leader who led the Free Soil Party ticket in the 1848 presidential election.

He was born in Kinderhook, New York, where most residents were of Dutch descent and spoke Dutch as their primary language. Van Buren is the only president to have spoken English as a second language. He entered politics as a member of the Democratic-Republican Party, won a seat in the New York State Senate, and was elected to the United States Senate in 1821. As the leader of the Bucktails faction of the party, Van Buren established the political machine known as the Albany Regency. He ran successfully for governor of New York to support Andrew Jackson's candidacy in the 1828 presidential election but resigned shortly after Jackson was inaugurated so he could accept appointment as Jackson's secretary of state. In the cabinet, Van Buren was a key Jackson advisor and built the organizational structure for the coalescing Democratic Party. He ultimately resigned to help resolve the Petticoat affair and briefly served as ambassador to the United Kingdom. At Jackson's behest, the 1832 Democratic National Convention nominated Van Buren for vice president, and he took office after the Democratic ticket won the 1832 presidential election.

Salmon Portland Chase (January 13, 1808 – May 7, 1873) was an American politician and jurist who served as the sixth chief justice of the United States from 1864 to his death in 1873. He earlier served as the 25th United States secretary of the treasury from 1861 to 1864, during the American Civil War in the Abraham Lincoln administration. Chase also served as the 23rd governor of Ohio from 1856 to 1860, and represented Ohio in the United States Senate from 1849 to 1855 and again in 1861. Chase is therefore one of the few American politicians who have held constitutional office in all three branches of the federal government, in addition to serving in the highest state-level office. From the 1850s onward, even as Chief Justice, Chase sought a presidential nomination that never came because he was considered inept.

Born in Cornish, New Hampshire, Chase studied law under Attorney General William Wirt before establishing a legal practice in Cincinnati. He became an anti-slavery activist and frequently defended fugitive slaves in court. Chase left the Whig Party in 1841 to become the leader of Ohio's Liberty Party. In 1848, he helped establish the Free Soil Party and recruited former President Martin Van Buren to serve as the party's presidential nominee. Chase won election to the Senate the following year, and he opposed the Compromise of 1850 and the Kansas–Nebraska Act. In the aftermath of the Kansas–Nebraska Act, Chase helped establish the Republican Party, which opposed the extension of slavery into the territories. After leaving the Senate, Chase served as the first Republican governor of Ohio from 1856 to 1860.

John Parker Hale (March 31, 1806 – November 19, 1873) was an American politician and lawyer from New Hampshire. He served in the United States House of Representatives from 1843 to 1845 and in the United States Senate from 1847 to 1853 and again from 1855 to 1865. He began his congressional career as a Democrat, but helped establish the anti-slavery Free Soil Party and eventually joined the Republican Party.

Born in Rochester, New Hampshire, Hale established a legal practice in Dover, New Hampshire after graduating from Bowdoin College. Hale won election to the New Hampshire House of Representatives in 1832 and served as the United States Attorney for New Hampshire under President Andrew Jackson and President Martin Van Buren. He won election to the United States House of Representatives in 1842 but was denied the party's nomination in 1844 due to his opposition to the annexation of Texas. After losing his seat, he continued to campaign against slavery and won election to the Senate in 1846 as an Independent Democrat. In the Senate, he strongly opposed the Mexican–American War and continued to speak against slavery.

Presidential elections were held in the United States on November 2, 1852. Democratic nominee Franklin Pierce defeated Whig nominee General Winfield Scott.

Incumbent Whig President Millard Fillmore had succeeded to the presidency in 1850 upon the death of President Zachary Taylor. Fillmore endorsed the Compromise of 1850 and enforced the Fugitive Slave Law. This earned Fillmore Southern voter support and Northern voter opposition. On the 53rd ballot of the sectionally divided 1852 Whig National Convention, Scott defeated Fillmore for the nomination. Democrats divided among four major candidates at the 1852 Democratic National Convention. On the 49th ballot, dark horse candidate Franklin Pierce won nomination by consensus compromise. The Free Soil Party, a third party opposed to the extension of slavery in the United States and into the territories, nominated New Hampshire Senator John P. Hale.

The Fugitive Slave Act or Fugitive Slave Law was a statute passed by the 31st United States Congress on September 18, 1850, as part of the Compromise of 1850 between Southern interests in slavery and Northern Free-Soilers.

The Act was one of the most controversial elements of the 1850 compromise and heightened Northern fears of a slave power conspiracy. It required that all escaped slaves, upon capture, be returned to the slave-owner and that officials and citizens of free states had to cooperate. The Act contributed to the growing polarization of the country over the issue of slavery. It was one of the factors that led to the founding of the Republican Party and the start of the American Civil War.
