The Constitutional Convention met during the spring and summer of 1787, with delegates from 12 states (Rhode Island did not send delegates to the convention). Delegates proposed, discussed and compromised each section, each clause of the new Constitution. Convention attendees received the final draft on September 12. Five days later, September 17, 1787, the Constitution was signed by 39 delegates. Delegates who refused to sign the Constitution were concerned about the loss of state's rights and the lack of a Bill of Rights.
