Fearing slave rebellion from its highly concentrated black population, the South wanted free access to the Territories to lessen this; the North wanted to restrict black people to the South and open the Territories to white-only immigration. A great irony of history is the blame the American South receives for African slavery: the South did not bring the black man to America, British and New England slave ships did after purchasing their human cargoes from African chieftains.
A War of Conquest, Not Philanthropy
“The initial sympathy of the British people for the North because of the belief that the South had seceded to set up a slave state and that the North stood for freedom of the slave was soon to be destroyed, and a strong conviction arose that the freedom of the slave was not an issue in the war. One can hardly escape the logic of events which forced this conclusion upon the English mind.
During the winter of [early] 1861, it will be recalled, numerous compromises of the American troubles were discussed, the most important of which was the Crittenden compromises conceding a permanent share of the territories to slavery. The Economist upon hearing of such proposals spoke of the measures as iniquitous, and was not willing to believe that Lincoln would yield to them.
But the final disillusionment came when in his inaugural address Lincoln said: “I have no purpose, directly or indirectly, to interfere with the institution of slavery in the States where is exists . . . I believe I have no lawful right to do so and I have no intention to do so. “
This was, in truth, the death knell of British sympathy based upon the moral righteousness of the Northern cause. If freedom was not the cause, then what was it?
The Economist late in the summer of 1861 pronounced a little stronger upon the issue of the war: It was not for freeing the slave on the part of the North or preserving slavery on the part of the South, but was for dominion and power on the part of the one and the right of self-government on the part of the other.
After Lincoln’s message to Congress, which was as tender of the rights of slavery as had been in his inaugural, the Economist was completely convinced, if there had been any doubts, that Lincoln and the North would be more than glad to continue or restore the old Federal union on the basis of slavery and all its abuses if the South would only return.
The inevitable conclusion was that the war was “a war of conquest and not of philanthropy.”
