On what date did Lincoln first win the presidency

By the time of Lincoln’s inauguration on March 4, 1861, seven states had seceded, and the Confederate States of America had been formally established, with Jefferson Davis as its elected president. One month later, the American Civil War began when Confederate forces under General P.G.T. Beauregard opened fire on Union-held Fort Sumter in South Carolina. In 1863, as the tide turned against the Confederacy, Lincoln emancipated the slaves and in 1864 won reelection. In April 1865, he was assassinated by Confederate sympathizer John Wilkes Booth at Ford’s Theatre in Washington, D.C. The attack came only five days after the American Civil War effectively ended with the surrender of Confederate General Robert E. Lee at Appomattox.

The 1860 United States presidential election was the 19th quadrennial presidential election. It was held on November 6, 1860. In a four-way contest, the Republican Party ticket of Abraham Lincoln and Hannibal Hamlin emerged triumphant. Lincoln's election served as the primary catalyst of the American Civil War.

The United States had become increasingly divided during the 1850s over sectional disagreements, primarily the extension of slavery into the territories. The incumbent president, James Buchanan, like his predecessor, Franklin Pierce, was a Northern Democrat with sympathies for the South. During the mid-to-late 1850s, the antislavery Republican Party became a major political force in the wake of the Kansas–Nebraska Act and the Supreme Court's decision in the 1857 case of Dred Scott v. Sandford. Starting in the 1856 United States presidential election and certainly by 1860, the Republican Party had replaced the defunct Whig Party as the major opposition to the Democrats. A group of former Whigs and Know Nothings formed the Constitutional Union Party, which sought to avoid secession by pushing aside the issue of slavery.
