Slave trade compromise

In August 1787, delegates at the Constitutional Convention in Philadelphia fought over whether Congress could regulate or end the Atlantic slave trade. Charles Cotesworth Pinckney and John Rutledge of South Carolina defended continued importation, while George Mason and Gouverneur Morris condemned the trade on moral and political grounds. The convention finally agreed that Congress could not prohibit the importation of enslaved people before 1808, though it could impose a tax on each person imported.

The compromise addressed a central political tension in Philadelphia: southern delegates wanted security for slavery, while other delegates feared that protecting the trade would stain the new republic and strengthen slaveholding interests. The bargain also showed how far the convention would go to keep South Carolina and Georgia inside the Union. Article I, Section 9 thus embedded slavery directly into the Constitution even as several delegates denounced the trade itself.

The 1808 deadline set by the convention led directly to the Act Prohibiting Importation of Slaves, which Congress passed effective January 1, 1808. The compromise also deepened the sectional logic that later reappeared in national conflicts over representation, expansion, and slavery.
