Final draft: 
 :*''Many Founding Fathers, including George Washington, Thomas Jefferson, and James Madison used slave labor on their respected plantations, farms, or estates.  The Constitution agreed to in 1787, sanctioned the system of slavery by counting slaves, or "human property", as 3/5 person in apportioning representation and a fugitive slave clause to capture and return runaway slaves. The Founding Fathers, however, did make important efforts to contain slavery. Many Northern states had adopted legislation to end or significantly reduce slavery after the American Revolution. Thomas Jefferson in 1784 proposed to ban slavery in all the Western Territories, having failed to pass Congress by one vote. Following Jefferson's plan Congress did ban slavery in the North West Ordinance of 1787. The international slave trade was banned in all states except South Carolina by 1800. Finally in 1807, President Jefferson signed into law a federally enforced ban on the international slave trade throughout all the United States and territories. President Jefferson, in 1804, however, allowed the domestic expansion or diffusion of slavery into the Louisiana Territory.
