Abraham Lincoln Elected President (1860)
Abraham Lincoln won the presidency on November 6, 1860, with about 40% of the popular vote in a four-way race, becoming the first Republican president. His election on a platform opposing the spread of slavery prompted South Carolina to secede the following month, followed by six more states before his inauguration. Lincoln led the Union through the Civil War, issued the Emancipation Proclamation and pushed the Thirteenth Amendment abolishing slavery through Congress.
