The Three-Fifths Compromise was a compromise reached between delegates from southern states and those from northern states during the 1787 United States Constitutional Convention. The debate was over if, and if so, how, slaves would be counted when determining a state's total population for legislative representation and taxing purposes. The issue was important, as this population number would then be used to determine the number of seats that the state would have in the United States House of Representatives for the next ten years. The effect was to give the southern states a third more seats in Congress and a third more electoral votes than they would otherwise have had, allowing the slave interests to largely dominate the government of the United States until 1865.[1] The compromise was proposed by delegates James Wilson and Roger Sherman.
