The Gettysburg Address, the most famous speech of Abraham Lincoln, was given at the Dedication of the Soldiers National Cemetery in the town of Gettysburg, Pennsylvania, USA, 19 November 1863, four months and a half later Battle of Gettysburg during the Civil War. 
Although Lincoln's carefully worded speech was secondary to the other speeches of the day, has been considered after one of the greatest speeches in the history of mankind. or at least one of the most famous and quoted in the modern era. Invoking the principles of equality of men enshrined in the Declaration of Independence, Lincoln redefined the Civil War as a new birth of freedom for the United States of America and its citizens.
Then select those words of Abraham Lincoln, which resonated throughout the United States and throughout history.
For eight decades and seven years, our parents were born 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 that is testing whether that nation or any nation so conceived and so dedicated, can long endure over time. We met on a great battlefield 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 for this nation might live. It is absolutely right and proper to do so.
But nevertheless 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 and above our poor power to add or subtract something. The world barely notice and do not long remember what we say now, but it can never forget what they did in this field.
We are, rather, we, the living, we must now devote ourselves to the unfinished work that those who fought here, they move so much and so nobly. While we are alive we must now devote ourselves to the great task still remaining before us-that from these honored dead to you, we take increased devotion to that cause for which they gave the last full measure of heat. We solve here, firmly, that these men have died in vain.
That this nation, under God, shall have a new birth of freedom.
And the government of the people, by the people and for the people shall not perish from the earth.
Abraham Lincoln
Abraham Lincoln was born on February 12, 1809 and died on April 15, 1865, was the sixteenth President of the United States and the first for the GOP.
As a strong opponent of the expansion of slavery in the United States, Lincoln won the Republican nomination in 1860 and was elected president later that year. During his tenure, he helped preserve the United States for the defeat of the secessionist Confederate States of America in the Civil War.
Introduced measures that resulted in the abolition of slavery, issuing his Emancipation Proclamation in 1863 and promoting the adoption of the Thirteenth Amendment to the Constitution in 1865.
Lincoln closely supervised the result of the war to an end, in particular the selection of the best generals, including Ulysses S. Grant. Lincoln successfully mobilized public opinion through his rhetoric and speeches, the Gettysburg Address is just one example.
After the war, Lincoln established the reconstruction, trying to gather quickly the country through a policy of generous reconciliation. His assassination in 1865 was the first assassination in the United States.
