If the Missouri Compromise of 1820 had extended the geographical boundary-line of slavery in the Territories, if the Kansas-Nebraska Bill of 1854 had erased every geographical boundary-line and set up a political barrier instead, the will of the majority of the settlers, now the Supreme Court of the United States, by its decision of 1857, tore down even this political barrier and transformed all the Territories of the republic, present and future, from nurseries of free states into nurseries of slavery.
At the same time, under Buchanan's government the severer law on the surrendering of fugitive slaves enacted in 1850 was ruthlessly carried out in the states of the North. To play the part of slave-catchers for the Southern slaveholders appeared to be the constitutional calling of the North. On the other hand, in order to hinder as far as possible the colonisation of the Territories by free settlers, the slaveholders' party frustrated all the so-called free-soil measures, i.e., measures which were to secure for the settlers a definite amount of uncultivated state land free of charge.
In the foreign, as in the domestic, policy of the United States, the interest of the slaveholders served as the guiding star. Buchanan had in fact bought the office of President through the issue of the Ostend Manifesto, in which the acquisition of Cuba, whether by purchase or by force of arms, was proclaimed as the great task of national policy. Under his government northern Mexico was already divided among American land speculators, who impatiently awaited the signal to fall on Chihuahua, Coahuila and Sonora.
The unceasing piratical expeditions of the filibusters against the states of Central America were directed no less from the White House at Washington.
In the closest connection with this foreign policy, whose manifest purpose was conquest of new territory for the spread of slavery and of the slaveholders'
rule, stood the reopening of the slave trade, secretly supported by the Union government. St[ephen] A. Douglas himself declared in the American Senate on August 20, 1859: During the last year more Negroes have been imported from Africa than ever before in any single year, even at the time when the slave trade was still legal. The number of slaves imported in the last year totalled fifteen thousand.
Armed spreading of slavery abroad was the avowed aim of national policy;the Union had in fact become the slave of the three hundred thousand slaveholders who held sway over the South. A series of compromises, which the South owed to its alliance with the Northern Democrats, had led to this result.
On this alliance all the attempts, periodically repeated since 1817, to resist the ever increasing encroachments of the slaveholders had hitherto come to grief. At length there came a turning point.
For hardly had the Kansas-Nebraska Bill gone through, which wiped out the geographical boundary-line of slavery and made its introduction into new Territories subject to the will of the majority of the settlers, when armed emissaries of the slaveholders, border rabble from Missouri and Arkansas, with bowie-knife in one hand and revolver in the other, fell upon Kansas and sought by the most unheard-of atrocities to dislodge its settlers from the Territory colonised by them. These raids were supported by the central government in Washington. Hence a tremendous reaction. Throughout the North, but particularly in the North-west, a relief organisation was formed to support Kansas with men, arms and money. Out of this relief organisation arose the Republican Party, which therefore owes its origin to the struggle for Kansas. After the attempt to transform Kansas into a slave Territory by force of arms had failed, the South sought to achieve the same result by political intrigues. Buchanan's government, in particular, exerted its utmost efforts to have Kansas included in the States of the Union as a slave state with a slave constitution imposed on it.
Hence renewed struggle, this time mainly conducted in Congress at Washington.
Even St[ephen] A. Douglas, the chief of the Northern Democrats, now (1857- 58) entered the lists against the government and his allies of the South, because imposition of a slave constitution would have been contrary to the principle of sovereignty of the settlers passed in the Nebraska Bill of 1854. Douglas, Senator for Illinois, a North-western state, would naturally have lost all his influence if he had wanted to concede to the South the right to steal by force of arms or through acts of Congress Territories colonised by the North. As the struggle for Kansas, therefore, called the Republican Party into being, it at the same time occasioned the first split within the Democratic Party itself.
The Republican Party put forward its first platform for the presidential election in 1856. Although its candidate, John Fremont, was not victorious, the huge number of votes cast for him at any rate proved the rapid growth of the Party, particularly in the North-west. At their second National Convention for the presidential election (May 17, 1860), the Republicans again put forward their platform of 1856, only enriched by some additions.
Its principal contents were the following: Not a foot of fresh territory is further conceded to slavery. The filibustering policy abroad must cease.
The reopening of the slave trade is stigmatised. Finally, free-soil laws are to be enacted for the furtherance of free colonisation.
The vitally important point in this platform was that not a foot of fresh terrain was conceded to slavery; rather it was to remain once and for all confined with the boundaries of the states where it already legally existed. Slavery was thus to be formally interned; but continual expansion of territory and continual spread of slavery beyond its old limits is a law of life for the slave states of the Union.
