Know Nothing in the context of "Catholic Church in the United States"

A United States presidential election was held on November 6, 1860. The Republican Party ticket of Abraham Lincoln and Hannibal Hamlin emerged victorious.

In 1860, the United States was divided over the issue of slavery. Four major political parties nominated candidates in the 1860 presidential election. Incumbent president James Buchanan, a Democrat, did not seek re-election. The anti-slavery Republican Party nominated Abraham Lincoln, a former one-term Whig Representative from Illinois, for president. Its platform promised not to interfere with slavery in the South, but opposed extension of slavery into the territories. A group of former Whigs and Know Nothings formed the Constitutional Union Party, which sought to avoid disunion by resolving divisions over slavery with some new compromise. The 1860 Constitutional Union Convention put forward former Tennessee Senator John Bell for president. After the 1860 Democratic National Convention adjourned without agreeing on a nominee, a second convention nominated Illinois Senator Stephen A. Douglas as the Democratic presidential candidate. Douglas's support for the concept of popular sovereignty, which called for each territory's settlers to decide locally on the status of slavery, alienated many radical pro-slavery Southern Democrats. With President Buchanan's support, Southern Democrats held their own convention, nominating Vice President John C. Breckinridge of Kentucky for president.

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.

The Constitutional Union Party was a political party which stood in the 1860 United States elections. It mostly consisted of conservative former Whigs from the Southern United States who wanted to avoid secession over slavery and refused to join either the Republican Party or Democratic Party. The Constitutional Union Party campaigned on a simple platform "to recognize no political principle other than the Constitution of the country, the Union of the states, and the Enforcement of the Laws".

The Whig Party collapsed in the 1850s due to a series of crises over slavery. Many former Whigs joined the new, anti-slavery Republican Party, but others joined the nativist American Party. The American Party declined after the 1856 elections, and for the 1860 elections John J. Crittenden and other former Whigs formed the Constitutional Union Party. The 1860 Constitutional Union Convention nominated John Bell of Tennessee for president and Edward Everett of Massachusetts for vice president. Party leaders hoped to force a contingent election in the House of Representatives by denying any one candidate a majority in the Electoral College.

Elections were held for the 35th United States Congress and the presidency of the United States, to serve from 1857 until 1861. The elections took place during a major national debate over slavery, with the issue of "Bleeding Kansas" taking center stage. Along with the 1854 elections, these elections occurred during the transitional period immediately preceding the Third Party System. Old party lines were broken; new party alignments along sectional lines were in the process of formation. The Republican Party absorbed the Northern anti-slavery representatives who had been elected in 1854 under the "Opposition Party" ticket (consisting largely of former Whigs) as the second-most powerful party in Congress. Minnesota and Oregon joined the union before the next election, and elected their respective congressional delegations to the 35th Congress.

In the presidential election, Democratic former Secretary of State James Buchanan defeated Republican General John Fremont and the American Party candidate, former President Millard Fillmore. Buchanan swept the South and split the North with Fremont, while Fillmore won Maryland. Buchanan had defeated incumbent President Franklin Pierce (the first elected president to lose his party's presidential nomination) and Senator Stephen A. Douglas of Illinois on the 17th ballot at the 1856 Democratic National Convention. Fremont defeated Supreme Court Justice John McLean at the 1856 Republican National Convention to take the Republican nomination. Fillmore's third-party candidacy took over twenty percent of the popular vote, the best popular vote showing by a third party until Theodore Roosevelt's 1912 candidacy.

Presidential elections were held in the United States on November 4, 1856. Democratic nominee James Buchanan defeated Republican nominee John C. Frémont and Know Nothing/Whig nominee Millard Fillmore. The main issue was the expansion of slavery as facilitated by the Kansas–Nebraska Act of 1854. Buchanan defeated President Franklin Pierce at the 1856 Democratic National Convention for the nomination. Pierce had become widely unpopular in the North because of his support for the pro-slavery faction in the ongoing civil war in territorial Kansas, and Buchanan, a former Secretary of State, had avoided the divisive debates over the Kansas–Nebraska Act by being in Europe as the Ambassador to the United Kingdom.

Slavery was the main issue, and with it the question of the survival of the United States as it then existed. The Democrats were seen as the pro-slavery party. While the new Republican party was hostile to slavery, they limited their efforts to the politically more manageable question of the extension of slavery into federal territories (and its removal from the District of Columbia). The nativist Know Nothings (known formally as the American Party) competed with the Republicans to replace the moribund Whig Party as the primary opposition to the Democrats. They emphasized opposition to Catholic immigrants.
