The Ordinance of 1787, a landmark act by the single camera Congress of the Confederation is passed on July 13, 1787. It established the Northwest Territory (The lands north and west of the Ohio River) and created a blueprint for westward expansion.
The Ordinance chartered a government for the Northwest Territory, provided a method for admitting new states to the Union from the territory, and listed a bill of rights guaranteed in the territory. Three principal provisions were ordained in the document:
1) A division of the Northwest Territory into "not less than three nor more than five States".
2) A three-stage method for admitting a new state to the Union .
3) A bill of rights protecting religious freedom, the right to a writ of habeas corpus, the benefit of trial by jury, and other individual rights; in addition the ordinance encouraged education, and forbade slavery. The ordinance mandated the creation of at least three but no more than five states from the region.
The territory eventually formed six States:
Ohio (1803)
Indiana (1816)
Illinois (1818)
Michigan (1837)
Wisconsin (1848)
Minnesota (1858) Borders adjusted later. More
