The slave trade compromise restricted the number of slaves counted toward representation and taxation to 3/5 the total number of slaves and prohibited congress from outlawing slavery before 1808. This compromise allowed the slave trade to continue for 20 years after the compromise was made.
The two major slave trade compromises were established to help quench the fears of the North and the South. The first compromise was enacted to help ease Northern worries that too many slaves were able to be represented for tax purposes. The second compromise was created to help ease Southern fears that they would not be able to continue their slave-trading practices.
