Why did Lincoln speak at Gettysburg, Pennsylvania?

Question:It was at the dedication of the military cemetery on the battleground of the Battle of Gettysburg.

Text:

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.

The Battle of Gettysburg was one of the bloodiest events in American History. Lincoln's speech was shortly after the battle was won. This was a political speech, was it meant to become what it became - well, I'm not sure it was. However, the tone and subject matter along with the timing - brought the reaction it did.

He was commemorating the cemetery that they put there after the Battle of Gettysburg.

If you've ever been to Gettysburg--just the size of the battlefield is unbelievable.
