Congress bans import of slaves
1808 · 19th Century
On March 2, 1807, President Thomas Jefferson signed the Act Prohibiting Importation of Slaves, barring the bringing of enslaved persons into the United States effective January 1, 1808 — the earliest date permitted under Article I, Section 9 of the Constitution. The legislation imposed penalties including fines and vessel forfeiture on violators. Despite the ban, illegal smuggling continued for decades, with an estimated 50,000 enslaved people illegally imported between 1808 and 1860. Domestic slave trading within states remained legal and expanded.
