Explanation:

The Northwest Ordinance was composed in 1787 and addressed the need for government in the territory acquired from the Treaty of Paris.

The Articles of Confederation wer the first written constitution but it was enough to govern and that started the Constitution.

The Declaration of Independence is a document written in 1776. If you remember from 6th or 7th grade History, you may have read about John Locke and how Thomas Jefferson used his ideas on social contract and natural right.

Hope this helps :)
