Form Dr. Boyd Cathey:
it was a war between two ideas of government, and, in reality, two ideas of history and progress. For the North, which now controlled the Federal government, it was a war to suppress what was seen as a rebellion against constituted national authority. For the states of the Southern Confederacy, it was a defense of their inherited and inherent rights under the old Constitution of 1787, rights that had never been ceded to the Federal government. And, more, it became for them a Second War for Independence against an arbitrary and overreaching government that had gravely violated that Constitution.
Thus, at Appomattox were set into motion momentous events in the future of the reconstituted American nation. With the defeat of the South, the restraints on industrial, and, eventually, international capitalism were removed. The road to centralized government power was cleared. But even more significantly, there was a sea change in what we might call “the dominant American philosophy.”
In the old ante-bellum Union the South had acted as a kind of counter-weight to the North and a quickly developing progressivist vision of history. Certainly, there were notable Southerners who shared the growing economic and political liberalism of their fellow citizens north of the Mason-Dixon Line (e.g, DeBow’s Review). Yet, increasingly in the late ante-bellum period, the most significant voices in the Southland echoed a kind of traditionalism somewhat reminiscent of the serious critiques being made in Europe of “the Idea of Progress” and of the deleterious effects of 19th century liberalism.
