On September 17th, 1787, the US Constitution was signed on the last day of the Constitutional Convention held in Philadelphia. The Constitution, however, would not be binding until nine of the Thirteen Colonies colonies ratified. On December 7th, the first five states signed: Delaware, Pennsylvania, New Jersey, Georgia and Connecticut. Other states, particularly Massachusetts, opposed the Constitution, and it was not until a compromise was reached that amendments would be added to the document that Massachusetts, Maryland, South Carolina, and finally New Hampshire agreed to sign. On September 25, 1789, the Bill of Rights was added, and North Carolina signed in November. In June 1788, Rhode Island ratified the Constitution as the last of the Thirteen Colonies.
