1860 United States presidential election in the context of "Confederate States of America"

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.

Abraham Lincoln (February 12, 1809 – April 15, 1865) was the 16th president of the United States, serving from 1861 until his assassination in 1865. He led the United States through the American Civil War, defeating the Confederate States and playing a major role in the abolition of slavery.

Lincoln was born into poverty in Kentucky and raised on the frontier. He was self-educated and became a lawyer, Illinois state legislator, and U.S. representative. Angered by the Kansas–Nebraska Act of 1854, which opened the territories to slavery, he became a leader of the new Republican Party. He reached a national audience in the 1858 Senate campaign debates against Stephen A. Douglas. Lincoln won the 1860 presidential election, prompting a majority of slave states to begin to secede and form the Confederate States. A month after Lincoln assumed the presidency, Confederate forces attacked Fort Sumter, starting the Civil War.

The Union is a term used to refer to the central government and loyal states of the United States during the American Civil War. Its military forces and civilian population resisted the purported secession of the slave states that formed the Confederate States of America following the 1860 election of Abraham Lincoln as president of the United States. Lincoln's administration asserted the permanency of the federal government and the continuity of the United States Constitution, and it refused to recognize the Confederate government.

Nineteenth-century Americans commonly used the term Union to mean either the federal government of the United States or the unity of the states within the federal constitutional framework. The Union can also refer to the people or territory of the states that remained loyal to the national government during the war. The loyal U.S states located mostly above the Mason–Dixon line were also known as the North, although four southern border states and the future state of West Virginia remained loyal to the Union, and Black Southerners and many Southern Unionists opposed secession and supported the Union war effort.

Hannibal Hamlin (August 27, 1809 – July 4, 1891) was an American politician and diplomat who was the 15th vice president of the United States, serving from 1861 to 1865, during President Abraham Lincoln's first term. He was the first Republican vice president.

As an attorney from Maine, Hamlin began his political career as a Democrat in the Maine House of Representatives before being elected twice to the United States House of Representatives, and then to the United States Senate. With his strong abolitionist views, he left the Democratic Party for the newly formed Republican Party in 1856. In the 1860 general election, Hamlin balanced the successful Republican ticket as a New Englander partnered with the Northwesterner Lincoln. Although not a close friend of the president, he lent loyal support to his key projects such as the Emancipation Proclamation during the American Civil War.

Southern Democrats are members of the U.S. Democratic Party who reside in the Southern United States.

Before the American Civil War, Southern Democrats mostly believed in Jacksonian democracy. In the 19th century, they defended slavery in the United States and promoted its expansion into the Western United States against the Free Soil opposition in the Northern United States. The United States presidential election of 1860 formalized the split in the Democratic Party and brought about the American Civil War. After the Reconstruction Era ended in the late 1870s, so-called redeemers were Southern Democrats who controlled all the southern states and disenfranchised African-Americans.

Stephen Arnold Douglas (né Douglass; April 23, 1813 – June 3, 1861) was an American politician and lawyer from Illinois. As a U.S. senator, he was one of two nominees of the badly split Democratic Party to run for president in the 1860 presidential election, which was won by Republican candidate Abraham Lincoln. Douglas had previously defeated Lincoln in the 1858 United States Senate election in Illinois, known for the pivotal Lincoln–Douglas debates. Earlier, Douglas was one of the brokers of the Compromise of 1850, which sought to avert a sectional crisis; to further deal with the volatile issue of extending slavery into the territories, Douglas became the foremost advocate of popular sovereignty, which held that each territory should be allowed to determine whether to permit slavery within its borders. This attempt to address the issue was rejected by both pro-slavery and anti-slavery advocates. Standing 5 feet 4 inches (1.63 m) tall, Douglas was nicknamed the "Little Giant" because he was short in physical stature but a forceful and dominant figure in politics.

Born in Brandon, Vermont, Douglas migrated to Jacksonville, Illinois, in 1833 to establish a legal practice. He experienced early success in politics as a member of the newly formed Democratic Party, serving in the Illinois House of Representatives and various other positions. He was appointed to the Supreme Court of Illinois in 1841. In 1843, he was elected to the U.S. House of Representatives and therefore resigned from the Supreme Court of Illinois. Douglas became an ally of President James K. Polk and favored the annexation of Texas and the Mexican–American War. He was one of four Northern Democrats in the House to vote against the Wilmot Proviso, which would have banned slavery in any territory acquired from Mexico.

Franklin Pierce (November 23, 1804 – October 8, 1869) was the 14th president of the United States, serving from 1853 to 1857. A northern Democrat who believed that the abolitionist movement was a fundamental threat to national unity, he alienated anti-slavery groups by signing the Kansas–Nebraska Act and enforcing the Fugitive Slave Act. Conflict between North and South continued after Pierce's presidency, and, following Abraham Lincoln's victory in the 1860 presidential election, the Southern states seceded, resulting in the American Civil War.

Pierce was born in New Hampshire; his father was state governor Benjamin Pierce. He served in the House of Representatives from 1833 until his election to the Senate, where he served from 1837 until his resignation in 1842. His private law practice was a success, and he was appointed New Hampshire's U.S. attorney in 1845. Pierce took part in the Mexican–American War as a brigadier general in the United States Army. Democrats saw him as a compromise candidate uniting Northern and Southern interests, and nominated him for president at the 1852 Democratic National Convention. He and running mate William R. King easily defeated the Whig Party ticket of Winfield Scott and William Alexander Graham in the 1852 presidential election.

The 1860 Constitutional Union National Convention met on May 9, 1860, in Baltimore, Maryland. It was the only national convention ever held by the Constitutional Union Party, which was organized largely by former Whig Party members from the Southern United States who opposed secession. The convention nominated former Senator John Bell of Tennessee for president and former Secretary of State Edward Everett of Massachusetts for vice president.

Bell won the presidential nomination on the second ballot of the convention, defeating Everett, Governor Sam Houston of Texas, Senator John J. Crittenden of Kentucky, former Governor William Alexander Graham of North Carolina, Associate Justice John McLean of Ohio, and several other candidates. In the 1860 presidential election, Bell and Everett finished third in the electoral vote and fourth in the popular vote.
