    U.S Constitution Timeline

  • Virginia becomes the first state to ratify the Articles on Confederation.

    The Articles of Confederation, which form the basis of the new government of the United States, are ratified by Virginia. Many people believe that the lack of a strong central government is a mistake but sign off on the Articles anyway because some type of government was needed.
  • The Constitutional Convention begins in Philadelphia.

    State delegates meet at the Constitutional Convention in Philadelphia. Debate over the idea of a strong central government would continue until September 17, when the Constitution is narrowly approved.
  • The U.S. Constitution is ratified.

    When New Hampshire becomes the 9th of the 13 states to ratify it, the Constitution becomes the law of the land. It was decided that the new government would take effect on March 4, 1789, when the U.S. Senate met for the first time.
  • The Bill of Rights is approved by Congress.

    Congress passes 12 amendments to the Constitution. Based in part on the English Bill of Rights, the Bill of Rights protects basic freedoms guaranteed to all American citizens, including freedom of speech and the right to bear arms. Two of the 12 amendments are not ratified.

    The 27th Amendment, which states that pay raises to members of Congress go into effect in the following Congressional session, is ratified. The amendment failed when it was presented as part of the Bill of Rights in 1789.
