Twenty-seventh Amendment to the United States Constitution
Congress sent the package of 12 amendments to the states on September 25, 1789.  For these amendments to be added to the Constitution, three-fourths of the state legislatures would have to ratify (approve) the amendments.  At the time, there were only 11 states (North Carolina and Rhode Island had not ratified the Constitution yet).  This meant just nine states would have to approve the amendments to add them to the Constitution.
