Union (and the liberal democracy it represented) and emancipation were not, after all, mutually exclusive goals. Unless the Union was restored, there… - Allen C. Guelzo

People today often want to separate slavery, and say that Lincoln was interested in preserving the union and not in destroying slavery. No, that gets it exactly wrong. The two are as knotted together as a rope, because the only union worth preserving is a union that has abjured slavery. So for Lincoln to get rid of slavery is to purge America of the aristocratic poison. He once said that slavery was the one retrograde institution that was poisoning the American republic, keeping the American republic from realizing its full potential.

To Lincoln, slavery undercut the free labor outlook on the world because it denied advancement and self-improvement. For Lincoln, the great attraction of any economic regime was the degree to which it permitted accumulation and self-promotion. He once described the ideal system as being one where the penniless beginner starts out working for somebody else, accumulates capital on his own by dint of savings, goes into business for himself, and then eventually becomes so successful that he hires others, who in turn continue the cycle. And he spoke of that as being the order of things in a society of equals. For him, the very notion of equality is a matter of equality of openness, aspiration, and opportunity.

Reconstruction aspired to restore the foundations of freedom to a wayward South and it expected to triumph as effortlessly as 19th-century liberal notions of progress had promised. Instead, the same Romantic feudalism that had created the old Southern order reasserted its hegemony, and postwar Southern aristocrats appealed to a set of cultural and racial biases which safely defused the importance of property, and sharply restricted access to it. This might have been averted had the victorious Union been willing to pour the resources into Reconstruction it had devoted to winning the war. But Reconstruction became a symbol of how quickly political fatigue afflicts liberal democracies. Moreover, understanding Reconstruction as a bourgeois revolution which was strangled in its cradle by vengeful cotton nabobs offers some larger parallels to the optimistic era that prevailed between the fall of the Berlin Wall and the rise of Islamic state terrorism.
