Constitutional Convention (United States) [SEP] Commerce and Slave Trade Compromise
During the convention's late July recess, the Committee of Detail had inserted language that would prohibit the federal government from attempting to ban international slave trading and from imposing taxes on the purchase or sale of slaves. The convention could not agree on these provisions when the subject came up again in late August, so they referred the matter to an eleven-member committee for further discussion. This committee helped work out a compromise: Congress would have the power to ban the international slave trade, but not for another twenty years (that is, not until 1808). In exchange for this concession, the federal government's power to regulate foreign commerce would be strengthened by provisions that allowed for taxation of slave trades in the international market and that reduced the requirement for passage of navigation acts from two-thirds majorities of both houses of Congress to simple majorities.
