Today, Sep. 17, 2013 marks 226 years since the United States Constitution was signed by the founders. The Constitution replaced the Articles of Confederation, which was created by the 13 former colonies after the American Revolution.
According to the Constitution Center, the United States Constitution was created at the Philadelphia Convention, which is now known as the Constitution Convention. The former colonies which were now known as states had sent 55 delegates to Philadelphia. Of those 55 delegates, only 39 delegates signed the Constitution.
The delegates signed on Sep. 17, 1787, at the same place that the founding fathers had signed the Declaration of Independence 11 years before Independence Hall in Philadelphia, Pa.
Here is a list of the signers of the U.S. Constitution as provided by the U.S. Archives:
