Lincoln, Abraham (1809–65) 16th president of the United States (1861–65), born in Hardin County, Kentucky. In Illinois, where he later settled, Lincoln pursued law and politics (as a Whig), serving in the state legislature (1834–41) and in the U.S. House of Representatives (1847–49), where he spoke out against the
Mexican War (1846–48). Prompted by the controversy over the expansion of slavery into the territories, he returned to public life in 1854. In 1858, though he lost the election, he gained national prominence when he challenged Stephen A. Douglas for the U.S. Senate and engaged him in a series of debates that brought the issue to a head. Nominated in 1860 for president on the Republican ticket, Lincoln carried the electoral vote despite winning slightly under 40 percent of the popular vote. Before his inauguration, in March 1861, seven of the ten states that would form the
Confederacy had already seceded. One month later, with the Southern capture of
Fort Sumter, the
Civil War had begun. Lincoln's intention, he said, was to preserve the Union and to stop the spread of slavery, not to attack it where it existed. Lincoln devoted most of his time to his duties as commander in chief, studying military history and strategy and frequently visiting troops at the front. He grew impatient with the failures of Union generals to act with the aggressiveness he believed necessary. Though Confederate successes (
First and
Second Bull Run, 1861–62) in the first two years of the war gave way to Union victories at
Gettysburg and
Vicksburg (both 1863), the conflict dragged on. Lincoln came to see that his hoped-for decisive victory that would end the war was not to be; the bloody and remorseless struggle would end only when the will of the South was broken. Weary of war and its costly human sacrifice, Northerners appeared ready in early 1864 to turn Lincoln out of office. But the victory at
Atlanta that year, followed by successes in the
Shenandoah Valley, restored their faith in the commander in chief and ensured his reelection on the Union ticket. The changes in fortune had come about with Lincoln's appointment of
Ulysses S. Grant as general in chief of all Union armies. Grant's strategy of attacking on several fronts at once was to be the key to the Union victory, which was effectively sealed with the surrender of
Robert E. Lee and his
Army of Northern Virginia at
Appomattox in April 1865. Five days later Lincoln was shot, the first president to be assassinated. He died the following morning (April 15). Though Lincoln has been criticized for exceeding his powers in curtailing civil liberties during the war, he remains a figure revered as the preserver of the republic and the destroyer of slavery. Though the
Emancipation Proclamation (1863) did not itself end that institution, it set the wheels in motion; and Lincoln himself proposed, but did not live to see enacted, a constitutional amendment to abolish slavery.
