The earlier Land Ordinance of 1784 was a resolution written by Thomas Jefferson calling for Congress to take action. The land west of the Appalachian Mountains, north of the Ohio River and east of the Mississippi River was to be divided into ten separate states. However, the 1784 resolution did not define the mechanism by which the land would become states, or how the territories would be governed or settled before they became states. The Ordinance of 1785 put the 1784 resolution in operation by providing a mechanism for selling and settling the land, while the Northwest Ordinance of 1787 addressed political needs.
