Illegal Slave Trade Continues After 1808 Ban — Tens of Thousands Smuggled In

Despite the federal ban effective January 1, 1808, the illegal importation of enslaved Africans continued for decades. Slave smuggling was widespread along the Gulf Coast, particularly through Spanish Florida and Louisiana bayous. Enforcement was deliberately weak: the U.S. Africa Squadron rarely had more than five vessels; prosecutions were almost never brought. Historians using slave ship databases estimate that 50,000–100,000 Africans were illegally imported between 1808 and 1860. The trade was an open secret; in 1820 Congress finally made slave trading a capital offense, though only one person — Captain Nathaniel Gordon in 1862 — was ever executed under the law.
