The Northwest Ordinance mandated the return of fugitive slaves who escaped into the Northwest Territory from other states where slavery was legal.

The Northwest Ordinance affirmed the “utmost good faith” towards the Indians, proclaimed that the Indians’ “lands and property shall never be taken from them without their consent,” and decreed that the “property, rights, and liberty” of Indians “shall never be invaded or disturbed, unless in just and lawful wars authorized by Congress.” (These provisions were generally ignored or circumvented as white settlers began driving Native Americans off their lands as early as the 1790s).

After ratification of the United States Constitution, the first U.S. Congress affirmed the provisions of the Northwest Ordinance (with slight changes) on August 7, 1789, by enacting a new bill entitled “An Act to provide for the Government of the Territory Northwest of the river Ohio.”

The Northwest Ordinance and its modified 1789 version established a blueprint for the formation of new states as the United States expanded west. Although the federal government later enacted several laws regarding westward expansion, they all embraced the principle that future states would enter the Union on equal footing with the existing states.
