defines the Constitution as the law of the land upon its ratification by 9 of the existing 13 states. Less than one year after it was proposed, 9 states did ratify the Constitution, but it was not until 1790 that all 13 states formally agreed.
Conventions to ratify the U.S. Constitution will be called in each of the 13 states. When 9 of the 13 states formally ratify the document, it will officially go into effect in those 9 states. It will apply to each additional state as each state ratifies the document.
This document was completed and agreed to unanimously by the undersigned delegates on September 17, 1787. [What follows is a list of 40 names, including George Washington, Alexander Hamilton, Benjamin Franklin, and James Madison.]
