Answer :
Land policy and territory administration were established by the Northwest Ordinances of 1785 and 1787. In the end, five states were formed out of the area plus a little section of the territory between the St. Lawrence River and the Mississippi River: Ohio, Illinois, Indiana, Michigan, and Wisconsin.
In 1803, Ohio became the first state to be formed from the Northwest Territory, and the remaining area was given the name Indiana Territory. The other four states were Illinois, Michigan, Wisconsin, and Indiana. The region also included a third of what would later become Minnesota.
The Northwest Ordinance, also known as the Ordinance of 1787, established a government for the Northwest Territory, laid out the procedure for adding a new state to the Union, and ensured that newly created states would be equally valuable to the original thirteen states.
