The territory was made up of lands beyond the Appalachian Mountains. It was south of British North America and the Great Lakes. It was north of the Ohio River. Article VI of the Northwest Ordinance prohibited slavery in the new territory. However, it contained a provision that any fugitive slaves caught in the territory would be returned to their owners. It also did not place any restrictions on slavery within any new states formed from the Northwest Territory. Southerners had no problems with the ban on slavery. They thought that most of the new settlers would come from Southern states. Once a state was formed, the former Southerners would vote to allow slavery. However, none of the states formed from the Northwest Territory ended up allowing slavery.
