Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.

Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this.

But, in a larger sense, we can not dedicate -- we can not consecrate -- we can not hallow -- this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us -- that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion -- that we here highly resolve that these dead shall not have died in vain -- that this nation, under God, shall have a new birth of freedom -- and that government of the people, by the people, for the people, shall not perish from the earth.

Burying the Dead at Gettysburg

From July 1 to July 3, 1863, the invading forces of General Robert E. Lee's Confederate Army clashed with the Army of the Potomac (under its newly appointed leader, General George G. Meade) at Gettysburg, some 35 miles southwest of Harrisburg, Pennsylvania. Casualties were high on both sides: Out of roughly 170,000 Union and Confederate soldiers, there were 23,000 Union casualties (more than one-quarter of the army's effective forces) and 28,000 Confederates killed, wounded or missing (more than a third of Lee's army). After three days of battle, Lee retreated towards Virginiaon the night of July 4. It was a crushing defeat for the Confederacy, and a month later the great general would offer Confederate President Jefferson Davis his resignation; Davis refused to accept it.

As after previous battles, thousands of Union soldiers killed at Gettysburg were quickly buried, many in poorly marked graves. In the months that followed, however, local attorney David Wills spearheaded efforts to create a national cemetery at Gettysburg. Wills and the Gettysburg Cemetery Commission originally set October 23 as the date for the cemetery's dedication, but delayed it to mid-November after their choice for speaker, Edward Everett, said he needed more time to prepare. Everett, the former president of Harvard College, former U.S. senator and former secretary of state, was at the time one of the country's leading orators. On November 2, just weeks before the event, Wills extended an invitation to President Lincoln, asking him "formally [to] set apart these grounds to their sacred use by a few appropriate remarks."

Gettysburg Address: Lincoln's Preparation

Though Lincoln was extremely frustrated with Meade and the Army of the Potomac for failing to pursue Lee's forces in their retreat, he was cautiously optimistic as the year 1863 drew to a close. He also considered it significant that the Union victories at Gettysburg and at Vicksburg, under General Ulysses S. Grant, had both occurred on the same day: July 4, the anniversary of the signing of theDeclaration of Independence.

When he received the invitation to make the remarks at Gettysburg, Lincoln saw an opportunity to make a broad statement to the American people on the enormous significance of the war, and he prepared carefully. Though long-running popular legend holds that he wrote the speech on the train while traveling to Pennsylvania, he probably wrote about half of it before leaving the White House on November 18, and completed writing and revising it that night, after talking with Secretary of State William H. Seward, who had accompanied him to Gettysburg.

The Historic Gettysburg Address

On the morning of November 19, Everett delivered his two-hour oration (from memory) on the Battle of Gettysburgand its significance, and the orchestra played a hymn composed for the occasion by B.B. French. Lincoln then rose to the podium and addressed the crowd of some 15,000 people. He spoke for less than two minutes, and the entire speech was only 272 words long. Beginning by invoking the image of the founding fathers and the new nation, Lincoln eloquently expressed his conviction that the Civil War was the ultimate test of whether the Union created in 1776 would survive, or whether it would "perish from the earth." The dead at Gettysburg had laid down their lives for this noble cause, he said, and it was up to the living to confront the "great task" before them: ensuring that "government of the people, by the people, for the people, shall not perish from the earth."

The essential themes and even some of the language of the Gettysburg Address were not new; Lincoln himself, in his July 1861 message to Congress, had referred to the United States as "a democracy–a government of the people, by the same people." The radical aspect of the speech, however, began with Lincoln's assertion that the Declaration of Independence–and not the Constitution–was the true expression of the founding fathers' intentions for their new nation. At that time, many white slave owners had declared themselves to be "true" Americans, pointing to the fact that the Constitution did not prohibit slavery; according to Lincoln, the nation formed in 1776 was "dedicated to the proposition that all men are created equal." In an interpretation that was radical at the time–but is now taken for granted–Lincoln's historic address redefined the Civil War as a struggle not just for the Union, but also for the principle of human equality.

Gettysburg Address: Public Reaction & Legacy

On the day following the dedication ceremony, newspapers all over the country reprinted Lincoln's speech along with Everett's. Opinion was generally divided along political lines, with Republican journalists praising the speech as a heartfelt, classic piece of oratory and Democratic ones deriding it as inadequate and inappropriate for the momentous occasion.

In the years to come, the Gettysburg Address would endure as arguably the most-quoted, most-memorized piece of oratory in American history. After Lincoln's assassination in April 1865, Senator Charles Sumner of Massachusettswrote of the address, "That speech, uttered at the field of Gettysburg...and now sanctified by the martyrdom of its author, is a monumental act. In the modesty of his nature he said 'the world will little note, nor long remember what we say here; but it can never forget what they did here.' He was mistaken. The world at once noted what he said, and will never cease to remember it."
