By the time of the Constitutional Convention in 1787, only Georgia still participated in the international slave trade, which had been abolished during the Revolution as part of the ban against trade with England. Nonetheless, Southern states were determined to protect the slave trade. A compromise, Article 1, Section 9 of the Constitution placed a possible time limit on the international trade, but did not end it. (It stated that Congress could not prohibit the "importation" of persons prior to 1808.)
Twenty years later, President Thomas Jefferson, who himself held deeply contradictory beliefs about the morality and legality of slavery, signed this act "to prohibit the importation of slaves in any port or place within the jurisdiction of the United States, from and after the first day of January [1808.]" Jefferson and Congress hoped to settle finally one aspect of the contentious issue of slavery by ending the international slave trade.
The Act imposed heavy penalties on international traders, but did not end slavery itself or the domestic sale of slaves. Not only did it drive trade underground, but ships caught illegally trading were often brought into the United States and its passengers sold into slavery.
