CaptionAbraham Lincoln, the defining figure of the era.

1860s in the United States was a decade of profound national crisis, cataclysmic war, and foundational transformation. The era was dominated by the American Civil War, a conflict that resolved the long-simmering disputes over slavery and states' rights but at a staggering human cost. Following the war, the nation entered the turbulent period of Reconstruction, grappling with the reintegration of the Confederate States of America and the emancipation of four million African Americans. The decade's events fundamentally reshaped the federal government, the national economy, and the social fabric of the country.

Political and governmental developments

The political landscape was shattered by the 1860 presidential election of Republican candidate Abraham Lincoln, which prompted the secession of eleven Southern states and the formation of the Confederate States of America under President Jefferson Davis. The United States Congress, now dominated by Northern Republicans, passed landmark legislation absent Southern opposition, including the Morrill Tariff, the Pacific Railroad Acts, and the Homestead Act. Key constitutional changes were enacted with the Thirteenth Amendment abolishing slavery, the Fourteenth Amendment guaranteeing citizenship and equal protection, and the Fifteenth Amendment protecting voting rights. The assassination of Abraham Lincoln in April 1865 thrust Andrew Johnson into the presidency, leading to a fierce clash with the Radical Republicans over the direction of Reconstruction.

The American Civil War

The American Civil War began with the Battle of Fort Sumter in April 1861 and engulfed the nation for four years. Major military campaigns were led by generals like Ulysses S. Grant, William Tecumseh Sherman, and Robert E. Lee. Decisive battles such as Antietam, Gettysburg, and the Siege of Vicksburg turned the tide in favor of the Union. The Emancipation Proclamation issued by Abraham Lincoln in 1863 redefined the war's purpose, making the abolition of slavery a central goal. The war concluded with Lee's surrender to Grant at Appomattox Court House in April 1865, followed by the surrender of remaining Confederate forces. The conflict resulted in over 600,000 military deaths and left much of the Southern United States, including cities like Atlanta and Richmond, in ruins.

Reconstruction era

The immediate post-war period, known as Reconstruction, was characterized by efforts to rebuild the South and define the status of newly freed African Americans. Congress established the Freedmen's Bureau to provide aid and established military districts to oversee the former Confederacy. The struggle between President Andrew Johnson and the Radical Republicans culminated in his impeachment by the House of Representatives in 1868, though he was acquitted by the Senate. New state governments formed under Reconstruction Acts saw the election of African-American officials to bodies like the South Carolina Legislature and the U.S. Congress, including Hiram Revels. However, this period also witnessed the rise of violent white supremacist groups like the Ku Klux Klan and the passage of Black Codes by Southern legislatures to restrict freedmen's rights.

Social and cultural changes

The abolition of slavery created a massive social revolution, as four million people sought to reunite families, establish independent communities, and build institutions like churches and schools. The Morrill Land-Grant Acts of 1862 spurred the creation of public universities, such as the University of California and Cornell University. Literature of the decade included Walt Whitman's war poetry in Drum-Taps and the publication of Louisa May Alcott's Little Women. The Plains Indians faced increased pressure from westward expansion, leading to conflicts like the Dakota War of 1862 and Red Cloud's War. Urbanization accelerated in Northern cities like New York City and Chicago, while the San Francisco press flourished.

The war economy industrialized the North, boosting industries in Philadelphia and Pittsburgh, while devastating the agrarian economy of the South. The federal government financed the war through the first income tax, war bonds, and the Legal Tender Act, which created a national paper currency known as "greenbacks". The Pacific Railroad Acts authorized the construction of the First transcontinental railroad, built by the Union Pacific Railroad and the Central Pacific Railroad, and completed in 1869 at Promontory Summit. Technological innovations included the widespread use of the telegraph, improvements in repeating rifles and ironclad warships like the USS Monitor, and the beginning of the Pennsylvania oil rush. The National Banking Acts created a uniform national banking system to stabilize the currency.
