[Non-Sequitur]

The Confederate Constitution prohibited the importation of slaves, so I believe it would have died out.

"The importation of negroes of the African race from any foreign country other than the slaveholding States or Territories of the United States of America, is hereby forbidden; and Congress is required to pass such laws as shall effectually prevent the same." -- Article 1, section 9, confederate constitution.

Try again.

Without importation of African Slaves, slavery would have eventually dwindled.
