Did they agree to wait 20 years to ban slavery?

Finally, a compromise was reached with the Southern states that guaranteed the continuance of the slave trade for 20 years after the adoption of the Constitution. That deal set the earliest expiration date as 1808 — which Congress met. Great Britain also banned the African slave trade in 1807.

So yes they agreed to wait 20 years
