The Lincoln Memorial is an American memorial built to honor the 16th President of the United States, Abraham Lincoln (February 12, 1809 – April 15, 1865), who led the country through a great constitutional, military and moral crisis the American Civil War preserving the Union while ending slavery and promoting economic and financial modernization.
In his House Divided Speech ,he said that,
A house divided against itself cannot stand. I believe this government cannot endure permanently half slave and half free. I do not expect the Union to be dissolved — I do not expect the house to fall — but I do expect it will cease to be divided. It will become all one thing, or all the other.
The Gettysburg Address is a speech by him and is one of the best—known speeches in United States history.In just over two minutes, Lincoln invoked the principles of human equality espoused by the Declaration of Independence and redefined the Civil War as a struggle not merely for the Union, but as "a new birth of freedom" that would bring true equality to all of its citizens, ensure that democracy would remain a viable form of government, and would also create a unified nation in which states' rights were no longer dominant.
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. ……
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.
