The Civil War may have been the catalyst for centralization of government. Interesting article. Here are a couple paragraphs:
With the orderly, legal secession of the southern states, the American genius for self-government reached its highest moral expression. Here was something unprecedented in history; a vast continental empire of republics torn by sectional, economic, and moral conflicts seeking to settle its differences not by war, but by peaceful secession of eleven contiguous republics, legitimated by the consent of the people. This was the very thing that, in 1840, John Quincy Adams said might be necessary in the future, and which the American commitment to self-government of peoples would legitimate, rather than a Union held together by bayonets. It was this also that President Buchanan had in mind when, although opposed to secession, he declared that the central government had no authority to coerce a seceding state. The same doctrine was asserted by Madison and Hamilton in the Federalist. Lincoln, however, like George III, was determined on coercion, but unlike the latter, he was also prepared to launch total war against the civilian population of the South to achieve the goal of a consolidated nationalism.
With Lincoln, then, a radical break occurs between the older Americanism that was grounded in the natural rights of substantial moral communities to govern themselves and a new Americanism grounded in the centralization and consolidation of power, and like the French Revolution, dedicated to an egalitarian doctrine of individualism. This doctrine, wherever it has been applied in the world, has required the destruction of independent social authorities and moral communities and the massive consolidation of power needed to achieve such destruction. Lincoln was a man of his age, and it was an age of unashamed empire building and of the coercion of independent political societies into consolidated unions. What Bismarck was accomplishing in Germany with a policy of “blood and iron,” and what Lenin would accomplish in Russia, Lincoln had accomplished in America. Lincoln did not preserve an organic indivisible union from destruction because he did not inherit one; rather, like Bismarck, he created one.
