The cultivation of the southern export articles, cotton, tobacco, sugar , etc., carried on by slaves, is only remunerative as long as it is conducted with large gangs of slaves, on a mass scale and on wide expanses of a naturally fertile soil, which requires only ****** labour. Intensive cultivation, which depends less on fertility of the soil than on investment of capital, intelligence and energy of labour, is contrary to the nature of slavery.
Hence the rapid transformation of states like Maryland and Virginia, which formerly employed slaves on the production of export articles, into states which raise slaves to export them into the deep South. Even in South Carolina, where the slaves form four-sevenths of the population, the cultivation of cotton has been almost completely stationary for years due to the exhaustion of the soil. Indeed, by force of circumstances South Carolina has already been transformed in part into a slave-raising state, since it already sells slaves to the sum of four million dollars yearly to the states of the extreme South and South-west. As soon as this point is reached, the acquisition of new Territories becomes necessary, so that one section of the slaveholders with their slaves may occupy new fertile lands and that a new market for slave-raising, therefore for the sale of slaves, may be created for the remaining section. It is, for example, indubitable that without the acquisition of Louisiana, Missouri and Arkansas by the United States, slavery in Virginia and Maryland would have been wiped out long ago. In the Secessionist Congress at Montgomery, Senator Toombs, one of the spokesmen of the South, strikingly formulated the economic law that commands the constant expansion of the territory of slavery. "In fifteen years," said he, "without a great increase in slave territory, either the slaves must be permitted to flee from the whites, or the whites must flee from the slaves."As is known, the representation of the individual states in the Congress House of Representatives depends on the size of their respective populations.
As the populations of the free states grow far more quickly than those of the slave states, the number of Northern Representatives was bound to outstrip that of the Southern very rapidly. The real seat of the political power of the South is accordingly transferred more and more to the American Senate, where every state, whether its population is great or small, is represented by two Senators. In order to assert its influence in the Senate and, through the Senate, its hegemony over the United States, the South therefore required a continual formation of new slave states. This, however, was only possible through conquest of foreign lands, as in the case of Texas, or through the transformation of the Territories belonging to the United States first into slave Territories and later into slave states, as in the case of Missouri, Arkansas, etc. John Calhoun, whom the slaveholders admire as their statesman par excellence, stated as early as February 19, 1847, in the Senate, that the Senate alone placed a balance of power in the hands of the South, that extension of the slave territory was necessary to preserve this equilibrium between South and North in the Senate, and that the attempts of the South at the creation of new slave states by force were accordingly justified.
Finally, the number of actual slaveholders in the South of the Union does not amount to more than three hundred thousand, a narrow oligarchy that is confronted with many millions of so-called poor whites, whose numbers have been constantly growing through concentration of landed property and whose condition is only to be compared with that of the Roman plebeians in the period of Rome's extreme decline. Only by acquisition and the prospect of acquisition of new Territories, as well as by filibustering expeditions, is it possible to square the interests of these poor whites with those of the slaveholders, to give their restless thirst for action a harmless direction and to tame them with the prospect of one day becoming slaveholders themselves.
A strict confinement of slavery within its old terrain, therefore, was bound according to economic law to lead to its gradual effacement, in the political sphere to annihilate the hegemony that the slave states exercised through the Senate, and finally to expose the slaveholding oligarchy within its own states to threatening perils from the poor whites. In accordance with the principle that any further extension of slave Territories was to be prohibited by law, the Republicans therefore attacked the rule of the slaveholders at its root. The Republican election victory was accordingly bound to lead to open struggle between North and South. And this election victory, as already mentioned, was itself conditioned by the split in the Democratic camp.
The Kansas struggle had already caused a split between the slaveholders'
party and the Democrats of the North allied to it. With the presidential election of 1860, the same strife now broke out again in a more general form. The Democrats of the North, with Douglas as their candidate, made the introduction of slavery into Territories dependent on the will of the majority of the settlers. The slaveholders' party, with Breckinridge as their candidate, maintained that the Constitution of the United States, as the Supreme Court had also declared, brought slavery legally in its train; in and of itself slavery was already legal in all Territories and required no special naturalisation. Whilst, therefore, the Republicans prohibited any extension of slave Territories, the Southern party laid claim to all Territories of the republic as legally warranted domains.
