What did the Three-Fifths Compromise do?
Slaves were counted as three fifth of a person for determining a states' population in the distribution of seats in the House of Representatives to gain Southern support for the Constitution.
On this date in 1787, the Three-fifths Compromise was enacted. Delegates to the Constitutional Convention in Philadelphia that year accepted a plan determining a state’s representation in the U.S. House of Representatives. It was ironic that it was a liberal northern delegate, James Wilson of Pennsylvania, who proposed the Three-Fifths Compromise, as a way to gain southern support for a new framework of government.
Southern states had wanted representation apportioned by population; after the Virginia Plan was rejected, the Three-Fifths Compromise seemed to guarantee that the South would be strongly represented in the House of Representatives and would have disproportionate power in electing Presidents.
The issue of how to count slaves split the delegates into two groups. The northerners regarded slaves as property who should receive no representation. Southerners demanded that Blacks be counted with whites. The compromise clearly reflected the strength of the pro-slavery forces at the convention. The “Three-fifths Compromise” allowed a state to count three fifths of each Black person in determining political representation in the House.
Rather than halting or slowing the importation of slaves in the south, slavery had been given a new life — a political life. Even when the law stopped the importing of new slaves in 1808, the south continued to increase its overall political status and electoral votes by adding and breeding slaves illegally. The Three-fifths Compromise would not be challenged again until the Dred Scott case in 1856.
