The Three-Fifths Compromise And The Debates Over Slavery

The Three-Fifths Compromise and the Debates over Slavery

The Great Compromise that determined the structure of Congress soon led to another debate, however. When states took a census of their population for the purpose of allotting House representatives, should slaves be counted? Southern states were adamant that they should be, while delegates from northern states were vehemently opposed, arguing that representatives from southern states could not represent the interests of enslaved people. If slaves were not counted, however, southern states would have far fewer representatives in the House than northern states did. For example, if South Carolina were allotted representatives based solely on its free population, it would receive only half the number it would have received if slaves, who made up approximately 43 percent of the population, were included.

The Three-Fifths Compromise resolved the impasse, although not in a manner that truly satisfied anyone. For purposes of Congressional apportionment, slaveholding states were allowed to count all their free population, including free African Americans and 60 percent (three-fifths) of their enslaved population. To mollify the north, the compromise also allowed counting 60 percent of a state’s slave population for federal taxation, although no such taxes were ever collected. Another compromise regarding the institution of slavery granted Congress the right to impose taxes on imports in exchange for a twenty-year prohibition on laws attempting to ban the importation of slaves to the United States, which would hurt the economy of southern states more than that of northern states. Because the southern states, especially South Carolina, had made it clear they would leave the convention if abolition were attempted, no serious effort was made by the framers to abolish slavery in the new nation, even though many delegates disapproved of the institution.

Indeed, the Constitution contained two protections for slavery. Article I postponed the abolition of the foreign slave trade until 1808, and in the interim, those in slaveholding states were allowed to import as many slaves as they wished.

Furthermore, the Constitution placed no restrictions on the domestic slave trade, so residents of one state could still sell enslaved people to other states. Article IV of the Constitution—which, among other things, required states to return fugitives to the states where they had been charged with crimes—also prevented slaves from gaining their freedom by escaping to states where slavery had been abolished. Clause 3 of Article IV (known as the fugitive slave clause) allowed slave owners to reclaim their human property in the states where slaves had fled.
