The Northwest Ordinance was a law passed by the Confederation Congress in 1787 to organize the land north of the Ohio River and east of the Mississippi River. This area became known as the Old Northwest Territory and later formed states such as Ohio, Indiana, Illinois, Michigan, Wisconsin, and part of Minnesota. The ordinance mattered because it showed how the United States could grow without simply turning western lands into colonies.

It created rules for government, rights, and eventual statehood.

Key Facts

  • The Northwest Ordinance was passed in 1787 under the Articles of Confederation.

  • New states admitted from the territory would enter the Union on equal footing with the original states.
  • The ordinance banned slavery in the Northwest Territory, although it included a fugitive slave clause.

Common Mistakes to Avoid

  • Saying the Northwest Ordinance was part of the Constitution is wrong because it was passed in 1787 under the Articles of Confederation before the Constitution took effect.
  • Thinking the ordinance created one large permanent territory is wrong because it established a path for the region to be divided into future states.
  • Assuming the slavery ban ended slavery in the entire United States is wrong because the ban applied only to the Northwest Territory.
  • Forgetting the equal footing principle is a mistake because the ordinance made new states equal to older states rather than subordinate colonies.

Practice Questions

  1. 1 The ordinance allowed a territory to apply for statehood at 60,000 free inhabitants. If a territory had 47,500 free inhabitants, how many more were needed to reach the requirement?
  2. 2 The Northwest Ordinance was passed in 1787, and Ohio became a state in 1803. How many years passed between the ordinance and Ohio statehood?
  3. 3 Explain why the Northwest Ordinance was important for U.S. civic development even though it was passed before the Constitution went into effect.
