The clause of the Constitution giving representation in the House of Representative of Congress and in the Electoral College in the choice of President and Vice-President, came soon to be regarded as unjust to the free States. Three fifths of all slaves were counted to give representation to free persons of the South; that is, three fifths of all slave property was counted numerically, and thus, in many Congressional districts, the vote of one slaveholder was more than equal to two votes in a free State. For example, in 1850, the number of free inhabitants in the slave States was 6,412,605, and in the free States, 13,434,686, more than double. The representation in Congress from the slave States was 90 members, from the free States 144. Three fifths of the slaves were 1,920,182, giving the South 20 (a fraction more) members, the ratio of representation then being 93,420. If the 234 representatives had been apportioned equally, according to free inhabitants, the North would have had 159 and the South 75, a gain of fifteen to the free and a loss of that number to the slave States, a gain of 30 to the North.
The same injustice was shown in levying direct taxes. (All this, however, has been changed by the Fourteenth Amendment to the Constitution.)
The same discriminating language is used (Sec. 9, Art. I.) when obviously referring to the African slave trade. A strong sentiment existed in favor of putting an end at once to the traffic in human being; the Christian consciences of our forefathers revolted at its wickedness, and there was then beginning a general movement throughout the civilized world against it. Some European countries had denounced it as piracy.
It was, however, profitable, and much capital was invested in it, and there was even then an increased demand for slaves in the cotton, rice, and tobacco States.
It was feared so radical a measure as the immediate stoppage of this trade would endanger the Constitution, and as to this, also, it was deemed wise to compromise; so Congress was prohibited from legislating to prevent it prior to the year 1808. This trade was not only then carried on by our own people, but, through ships of other countries, slaves were imported into the United States. Each State was left free to prohibit the importation of slaves within its limits.
We have now referred to all the clauses of the Constitution as originally adopted relating, by construction or possibility, to slavery or slave labor.
The Republic, under this great charter, set out upon the career of a nation, properly aspiring to become of the first among the powers of the earth, and succeeding in the higher sense in this ambition, it yet remains to be told how near our Republic came, in time, to the brink of that engulfing chasm which in past ages has swallowed up other nations for their wicked oppression and enslavement of man.
Slavery, thus delicately treated in our Constitution, brought that Republic, in less than three quarters of a century, to the throes of death, as we shall see.
VII CAUSES OF GROWTH OF SLAVERY
It may be well here, before speaking of slavery in its legislative history under the Constitution, to refer briefly to some of the more important causes of its growth and extension, other than political.
