Just like the colonies did with England, the seceding states listed the grievances that led to secession. The southerners said that the reason they were seceding was slavery, over and over. Don't know why you don't believe them now.
Georgia:
The people of Georgia having dissolved their political connection with the Government of the United States of America, present to their confederates and the world the causes which have led to the separation. For the last ten years we have had numerous and serious causes of complaint against our non-slave-holding confederate States with reference to the subject of African slavery. They have endeavored to weaken our security, to disturb our domestic peace and tranquility, and persistently refused to comply with their express constitutional obligations to us in reference to that property, and by the use of their power in the Federal Government have striven to deprive us of an equal enjoyment of the common Territories of the Republic. This hostile policy of our confederates has been pursued with every circumstance of aggravation which could arouse the passions and excite the hatred of our people, and has placed the two sections of the Union for many years past in the condition of virtual civil war. Our people, still attached to the Union from habit and national traditions, and averse to change, hoped that time, reason, and argument would bring, if not redress, at least exemption from further insults, injuries, and dangers. Recent events have fully dissipated all such hopes and demonstrated the necessity of separation.
Mississippi
In the momentous step which our State has taken of dissolving its connection with the government of which we so long formed a part, it is but just that we should declare the prominent reasons which have induced our course.
Our position is thoroughly identified with the institution of slavery-- the greatest material interest of the world. Its labor supplies the product which constitutes by far the largest and most important portions of commerce of the earth. These products are peculiar to the climate verging on the tropical regions, and by an imperious law of nature, none but the black race can bear exposure to the tropical sun. These products have become necessities of the world, and a blow at slavery is a blow at commerce and civilization. That blow has been long aimed at the institution, and was at the point of reaching its consummation. There was no choice left us but submission to the mandates of abolition, or a dissolution of the Union, whose principles had been subverted to work out our ruin. That we do not overstate the dangers to our institution, a reference to a few facts will sufficiently prove.
South Carolina
We hold that the Government thus established is subject to the two great principles asserted in the Declaration of Independence; and we hold further, that the mode of its formation subjects it to a third fundamental principle, namely: the law of compact. We maintain that in every compact between two or more parties, the obligation is mutual; that the failure of one of the contracting parties to perform a material part of the agreement, entirely releases the obligation of the other; and that where no arbiter is provided, each party is remitted to his own judgment to determine the fact of failure, with all its consequences.
In the present case, that fact is established with certainty. We assert that fourteen of the States have deliberately refused, for years past, to fulfill their constitutional obligations, and we refer to their own Statutes for the proof.
The Constitution of the United States, in its fourth Article, provides as follows: "No person held to service or labor in one State, under the laws thereof, escaping into another, shall, in consequence of any law or regulation therein, be discharged from such service or labor, but shall be delivered up, on claim of the party to whom such service or labor may be due."
This stipulation was so material to the compact, that without it that compact would not have been made. The greater number of the contracting parties held slaves, and they had previously evinced their estimate of the value of such a stipulation by making it a condition in the Ordinance for the government of the territory ceded by Virginia, which now composes the States north of the Ohio River.
The same article of the Constitution stipulates also for rendition by the several States of fugitives from justice from the other States.
Texas
When we advert to the course of individual non-slave-holding States, and that a majority of their citizens, our grievances assume far greater magnitude.
The States of Maine, Vermont, New Hampshire, Connecticut, Rhode Island, Massachusetts, New York, Pennsylvania, Ohio, Wisconsin, Michigan and Iowa, by solemn legislative enactments, have deliberately, directly or indirectly violated the 3rd clause of the 2nd section of the 4th article [the fugitive slave clause] of the federal constitution, and laws passed in pursuance thereof; thereby annulling a material provision of the compact, designed by its framers to perpetuate the amity between the members of the confederacy and to secure the rights of the slave-holding States in their domestic institutions-- a provision founded in justice and wisdom, and without the enforcement of which the compact fails to accomplish the object of its creation. Some of those States have imposed high fines and degrading penalties upon any of their citizens or officers who may carry out in good faith that provision of the compact, or the federal laws enacted in accordance therewith.
In all the non-slave-holding States, in violation of that good faith and comity which should exist between entirely distinct nations, the people have formed themselves into a great sectional party, now strong enough in numbers to control the affairs of each of those States, based upon an unnatural feeling of hostility to these Southern States and their beneficent and patriarchal system of African slavery, proclaiming the debasing doctrine of equality of all men, irrespective of race or color-- a doctrine at war with nature, in opposition to the experience of mankind, and in violation of the plainest revelations of Divine Law. They demand the abolition of negro slavery throughout the confederacy, the recognition of political equality between the white and negro races, and avow their determination to press on their crusade against us, so long as a negro slave remains in these States.
For years past this abolition organization has been actively sowing the seeds of discord through the Union, and has rendered the federal congress the arena for spreading firebrands and hatred between the slave-holding and non-slave-holding States.
Virginia
The people of Virginia, in their ratification of the Constitution of the United States of America, adopted by them in Convention on the twenty-fifth day of June, in the year of our Lord one thousand seven hundred and eighty-eight, having declared that the powers granted under the said Constitution were derived from the people of the United States, and might be resumed whensoever the same should be perverted to their injury and oppression; and the Federal Government, having perverted said powers, not only to the injury of the people of Virginia, but to the oppression of the Southern Slaveholding States.
