Today in history 149 years ago - the Gettysburg Address

This anniversary could not be more appropriate as ignorant, shallow, foolish people bring up stupid issues of secession.
Shame on them, and never more so than on this anniversary.

How appropriate that it was Texas v. White that decided and affirmed the civil war determined states may not leave the union by simple declaration - or petition, but that rather in the same way that a state had the approval of the other states to join the Union, they must have the formal consent of those other states that form the United States to leave that Union.

From that decision, by way of Wikipedia: The following are excerpts from the majority decision made by the Supreme Court Justices.

The Union of the States never was a purely artificial and arbitrary relation. It began among the Colonies, and grew out of common origin, mutual sympathies, kindred principles, similar interests, and geographical relations. It was confirmed and strengthened by the necessities of war, and received definite form and character and sanction from the Articles of Confederation. By these, the Union was solemnly declared to 'be perpetual.' And when these Articles were found to be inadequate to the exigencies of the country, the Constitution was ordained 'to form a more perfect Union.' It is difficult to convey the idea of indissoluble unity more clearly than by these words. What can be indissoluble if a perpetual Union, made more perfect, is not?^[7]

 When, therefore, Texas became one of the United States, she entered into an indissoluble relation. All the obligations of perpetual union, and all the guaranties of republican government in the Union, attached at once to the State. The act which consummated her admission into the Union was something more than a compact; it was the incorporation of a new member into the political body. And it was final. The union between Texas and the other States was as complete, as perpetual, and as indissoluble as the union between the original States. There was no place for reconsideration or revocation, except through revolution or through consent of the States.^[7]

Considered therefore as transactions under the Constitution, the ordinance of secession, adopted by the convention and ratified by a majority of the citizens of Texas, and all the acts of her legislature intended to give effect to that ordinance, were absolutely null. They were utterly without operation in law. The obligations of the State, as a member of the Union, and of every citizen of the State, as a citizen of the United States, remained perfect and unimpaired. It certainly follows that the State did not cease to be a State, nor her citizens to be citizens of the Union. If this were otherwise, the State must have become foreign, and her citizens foreigners. The war must have ceased to be a war for the suppression of rebellion, and must have become a war for conquest and subjugation.^[7]

The authority for the performance of the first had been found in the power to suppress insurrection and carry on war; for the performance of the second, authority was derived from the obligation of the United States to guarantee to every State in the Union a republican form of government. The latter, indeed, in the case of a rebellion which involves the government of a State and for the time excludes the National authority from its limits, seems to be a necessary complement to the former.^[7]

It is not necessary to attempt any exact definitions within which the acts of such a State government must be treated as valid or invalid. It may be said, perhaps with sufficient accuracy, that acts necessary to peace and good order among citizens, such for example, as acts sanctioning and protecting marriage and the domestic relations, governing the course of descents, regulating the conveyance and transfer of property, real and personal, and providing remedies for injuries to person and estate, and other similar acts, which would be valid if emanating from a lawful government must be regarded in general as valid when proceeding from an actual, though unlawful, government, and that acts in furtherance or support of rebellion against the United States, or intended to defeat the just rights of citizens, and other acts of like nature, must, in general, be regarded as invalid and void.^[7]

Address Delivered at the Dedication of the Cemetery at Gettysburg
Abraham Lincoln
November 19, 1863

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 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.
