The Whig party, whose great leader, Henry Clay, had closed his life in 1852, just at the time when Lincoln was becoming prominent in politics, held that all citizens were bound by the compact entered into by their ancestors, first under the Articles of Confederation of 1783, and later under the Constitution of 1789. Our ancestors had, for the purpose of bringing about the organisation of the Union, agreed to respect the institution of slavery in the States in which it existed. The Whigs of 1850, held, therefore, that in such of the Slave States as had been part of the original thirteen, slavery was an institution to be recognised and protected under the law of the land. They admitted, further, that what their grandfathers had done in 1789, had been in a measure confirmed by the action of their fathers in 1820. The Missouri Compromise of 1820, in making clear that all States thereafter organised north of the line thirty-six thirty were to be Free States, made clear also that States south of that line had the privilege of coming into the Union with the institution of slavery and that the citizens in these newer Slave States should be assured of the same recognition and rights as had been accorded to those of the original thirteen. The Missouri Compromise permitted also the introduction of Missouri itself into the Union as a Slave State (as a counterpoise to the State of Maine admitted the same year), although almost the entire territory of the State of Missouri was north of the latitude 36° 30'. We may recall that, under the Constitution, the States of the South, while denying the suffrage to the negro, had secured the right to include the negro population as a basis for their representation in the lower House. In apportioning the representatives to the population, five negroes were to be counted as the equivalent of three white men. The passage, in 1854, of the Kansas-Nebraska Act, the purpose of which was to confirm the existence of slavery and to extend the institution throughout the country, was carried in the House by thirteen votes. The House contained at that time no less than twenty members representing the negro population. The negroes were, therefore, in this instance involuntarily made the instruments for strengthening the chains of their own serfdom.
