On March 2, 1807, the U.S. Congress passes an act to “prohibit
the importation of slaves into any port or place within the
jurisdiction of the United States…from any foreign kingdom,
place, or country.” It would go into effect at the start of the
following year.

Following its ratification by the requisite three-quarters of the
states earlier in the month, the 13th Amendment is formally
adopted into the U.S. Constitution, ensuring that “neither
slavery nor involuntary servitude… shall exist within the
United States, or any place subject to their jurisdiction.”

The U.S. Congress IN 1807 passed an act to “prohibit the importation
of slaves into any port or place within the jurisdiction of the United
States…from any foreign kingdom, place, or country.”
