In 1803, Congress passed a bill that would become effective in 1808, which prohibited bringing to the country “Negro and mulatto” immigrants. The law applied to black freemen, not to black slaves.
Isn't it interesting that it did not apply to slaves, only free blacks and was effective after the date in Article I, § 9, clause 1, of the Constitution?
