Happy birthday, U.S. Constitution
Today, 17 September, is the anniversary of the signing of the Constitution by the delegates to the Philadelphia Convention. Their appointed task was to propose amendments to the Articles of Confederation -- which could only be amended by unanimous vote of the 13 states. Instead, the delegates proposed a completely new Constitution (although it did pick up a few points from the Articles) to come into effect when ratified by popular conventions in nine of the states.
The Constitution proudly proclaims that it was adopted by the "Unanimous Consent of the States present," but one state was missing. Do you know which one? It was Rhode Island, which never sent delegates to the Convention and was the last of the 13 to ratify the Constitution.
