Three-Fifths Wrong: What the Constitution Actually Did About Slavery

We know from experience that it's difficult to distill an event to a sentence or even to a paragraph and accurately capture its fullness or its context and implications. Leaving important voids in the storytelling leaves it to others to tell it their own way to the point that they might distort the facts and the story.

But the retelling of history is full of examples where that very thing happens, where the story is told and retold inaccurately. Sometimes it's done to illustrate a broader point. Sometimes it happens to make the history easier to follow and more relatable to students. Sometimes it arises out of mythmaking where over time, the myth takes on the appearance of truth.

Take Mason Locke Weems for example. In his "The Life of Washington," Parson Weems wrote that young Washington damaged his father's cherry tree and confessed as much to him: "I cannot tell a lie...I did cut it with my hatchet." Some retelling has it that he didn't just cut the tree, he chopped the whole thing down, which made his confession even bolder and more heroic because the wrongdoing he confessed to was more serious. And that was why Weems manufactured the anecdote: to convey to children the importance of honesty and to hold Washington up as a model of character and exemplary morality. (He also wanted to sell books.) But it was fiction.

There are a lot of other examples of distortion and simplification of history.

For instance, the Three-Fifths Compromise is often cited as proof that the Framers of the Constitution believed Black Americans were less than fully human. That characterization is widespread, but it's historically imprecise, likely arising out of a desire to emphasize the inhumanity of slavery. But the clause wasn't a statement about human worth. It was a political compromise over representation and taxation during the Constitutional Convention.

If we stop at correcting the record, we miss the larger point—the connection between the Constitution and slavery that helped shape the course of American history. We also miss something just as important: that while the Constitution remains one of the most enduring governing documents ever written, it was not without flaws—and that confronting and correcting those flaws is part of its legacy.

During the debate over representation at the Constitutional Convention, Southern states pressed to have enslaved people fully counted in determining how many representatives they would be allotted in Congress. They insisted on that despite the fact that enslaved people couldn't vote, hold office, or exercise any political rights. At the same time, Southern delegates resisted the idea that those same individuals should be fully counted for taxation purposes.

Northern delegates objected—not because they denied the humanity of enslaved people, but because counting them would increase the political power of states that denied them any rights. If counted fully, the South would gain additional seats in Congress and greater influence in presidential elections while those who were counted had no voice in government. With enough votes in Congress, Southern states could put off any effort to end the slave trade and slavery. The dispute, at its core, was over power.

The issue of slavery evoked strong reactions among Constitutional Convention delegates that revealed a deep division between North and South on the subject as delegates spoke with striking bluntness about it.

Gouverneur Morris of Pennsylvania was one of the most outspoken critics of slavery. In fact, he condemned it outright: “Slavery is a nefarious institution… It is the curse of heaven on the States where it prevails.” He also exposed the contradiction at the heart of the Southern position: “Are they men? Then make them citizens and let them vote. Are they property? Why then is no other property included?”

Others echoed that criticism. James Madison of Virginia was equally direct in saying that slavery undermined the very principles of representation and the consent of the governed. "Where slavery exists, the Republican theory becomes still more fallacious." George Mason, also of Virginia and himself a slaveholder, warned that slavery was “a slow poison” corrupting the nation’s morals and that every slaveholder "is born a petty tyrant." He said, "They bring the judgment of heaven on a country."

On the other side, some delegates dispensed with moral arguments altogether. John Rutledge stated plainly that slavery was a matter of pragmatic self-interest and economic necessity, not of religion and humanity which “have nothing to do with this question." He said, "Interest alone is the governing principle with nations.”

Charles Cotesworth Pinckney, also of South Carolina, made the stakes explicit: "South Carolina and Georgia cannot do without slaves..." He said that North Carolina, South Carolina, and Georgia would not join the Union if their interests in slavery and the slave trade were threatened.

Oliver Ellsworth, of Connecticut, like others, chose compromise for the sake of national unity. "Let every State import what it pleases...The morality or wisdom of slavery are considerations belonging to the States themselves."

But the Convention delegates, caught between these positions and aware that failure could dissolve the fragile Union, agreed to the Three-Fifths Compromise. Enslaved people would be counted as three-fifths for purposes of representation and taxation. It was the middle ground.

But focusing on the Three-Fifths Compromise alone misses the larger constitutional picture: that it not only resolved the representation and taxation question, it was one of several concessions that helped embed slavery into the structure of the federal government by protecting the slave trade until 1808 and providing slaveholders the right to recover fugitive slaves, even when they took refuge in free states.

Article I, Section 9, Clause 1 of the U.S. Constitution prohibited Congress from banning the importation of enslaved people before 1808, allowing the transatlantic slave trade to continue for twenty years. Although a modest duty—up to ten dollars—could be imposed, it wasn't enough to discourage the trade. When the restriction expired, Congress acted quickly, passing the Act Prohibiting Importation of Slaves, which took effect on January 1, 1808 and ended the legal importation of slaves into the United States. Illegal smuggling, however, continued.

The Constitution also required the return of fugitive slaves to slaveholders. Article IV, Section 2, Clause 3 provided that a person “held to Service or Labour” who escaped into another state must be delivered back to the slaveholder. This provision extended the reach of slavery beyond the South and made its enforcement a national obligation. It became one of the most contentious and destabilizing features of the Constitution, fueling conflict between free states and slave states for decades.

The Slave Trade Clause expired in 1808 but the Fugitive Slave Clause persisted until after the Civil War when passage of the Thirteenth Amendment nullified it. The Union's victory in the Civil War reshaped the political landscape. It enabled the Republicans to secure passage of the Thirteenth, Fourteenth, and Fifteenth Amendments—changes that would have been impossible before the war, when Southern states had the power to block them. After the war, ratification of the amendments became a condition of readmission to the Union.

The Three-Fifths Compromise was never an ideal solution, even to those who accepted it. It was a pragmatic bargain struck to secure agreement on a new constitutional framework. But the burden of that agreement—and other slavery-related compromises—was the incorporation of unresolved moral and political contradictions into the nation’s founding document.

The oversimplification of the Compromise to mean that the Framers valued Black Americans at “three-fifths of a person” risks obscuring the more important truth: that although the Constitution didn't define human worth in fractions, it did, in multiple ways, bend to the demands of a system that denied it. Over time, those contradictions didn't fade, they deepened.

Missing that detail shifts our attention away from the truly troublesome parts of our founding document that took eighty years and a brutal civil war to resolve.
