“I eagerly await the justification of slavery.”
In the context of the time it was not slavery that needed to be justified, but the far more radical proposition of abolition. Slavery had been a facet of every human culture for millennia and it was accepted as a norm until the late 18th century.
The Civil War was not started over slavery and as proof of that is the fact that slavery was not abolished in the Northern states until December of 1865 - several months after the end of the war.
I have to disagree. Slavery was under pressure all over the western world and several perfectly valid justifications for abolition were widely held, even in the South. For instance, it is often overlooked that the Dred Scott decision overturned a southern court's decision to free DS.
The tough issue of the day was what to do with the negros. No one, North or South, thought that this alien African population would or should ever be integrated into American society. So what do you do with them after freeing them? The South looked to the western territories as the answer to the question, states like Illinois were willing to go to war to kill that idea.
Really? I thought I saw a reference to that somewhere...ah yes:
Declarations of Secession
South Carolina
The people of the State of South Carolina, in Convention assembled, on the 26th day of April, A.D., 1852, declared that the frequent violations of the Constitution of the United States, by the Federal Government, and its encroachments upon the reserved rights of the States, fully justified this State in then withdrawing from the Federal Union; but in deference to the opinions and wishes of the other slaveholding States, she forbore at that time to exercise this right. Since that time, these encroachments have continued to increase, and further forbearance ceases to be a virtue.
Mississippi
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.
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.
Texas
Texas abandoned her separate national existence and consented to become one of the Confederated Union to promote her welfare, insure domestic tranquility and secure more substantially the blessings of peace and liberty to her people. She was received into the confederacy with her own constitution, under the guarantee of the federal constitution and the compact of annexation, that she should enjoy these blessings. She was received as a commonwealth holding, maintaining and protecting the institution known as negro slavery-- the servitude of the African to the white race within her limits-- a relation that had existed from the first settlement of her wilderness by the white race, and which her people intended should exist in all future time. Her institutions and geographical position established the strongest ties between her and other slave-holding States of the confederacy. Those ties have been strengthened by association. But what has been the course of the government of the United States, and of the people and authorities of the non-slave-holding States, since our connection with them?
Now mind you, I've only excerpted from these Declarations of Secession, but what I've presented clearly shows the prominence that the institution of slavery had for those secessionists.
