Answer:
1808.
Explanation:
<em>"There is a sense in which the Clause is no longer constitutionally relevant since it expired in 1808. At the time the Constitution was adopted, there was no guarantee whether or when the federal Congress would act to prohibit the importation of slaves. So there is a legitimate inquiry about what took place in the political realm over the 20-year period between the adoption of the Constitution and 1808. During that time period, popular support for the abolition of the slave trade and slavery itself increased both in the United States and in other countries. There was more support for restricting the slave trade initially than slavery itself in this time period. In the 1790s, Congress passed statutes regulating the trade in slaves by U.S. ships on the high seas. The United Kingdom and other countries also passed legislation restricting the slave trade, increasing international pressure on the United States to likewise curb the practice."</em>
