when was the constitution ratified by the states
Timeline of drafting and ratification of the United States Constitution The drafting of the Constitution of the United States began on May 25, 1787, when the Constitutional Convention met for the first time with a quorum at the Pennsylvania State House (now Independence Hall) in Philadelphia, Pennsylvania to revise the Articles of Confederation, and ended on September 17, 1787, the day the Constitution drafted by the convention's delegates to replace the Articles was adopted and signed. The ratification process for the Constitution began that day, and ended when the final state, Rhode Island, ratified it on May 29, 1790. In addition to key events during the Constitutional Convention and afterward while the Constitution was before the states for their ratification, this timeline includes important events that occurred during the run-up to the convention and during the nation's transition from government under the Articles of Confederation to government under the Constitution, and concludes with the unique ratification vote of Vermont, which at the time was a sovereign state outside the Union. The time span covered is 5 years, 9 months, from March 25, 1785 to January 10, 1791.
Signing of the United States Constitution The Signing of the United States Constitution occurred on September 17, 1787, at Independence Hall in Philadelphia, Pennsylvania, when 39 delegates to the Constitutional Convention, representing 12 states (all but Rhode Island, which declined to send delegates), endorsed the Constitution created during the four-month-long convention. In addition to signatures, this endorsement, the Constitution's eschatocol, included a brief declaration that the delegatesâ€™ work has been successfully completed and that those whose signatures appear on it subscribe to the final document. Included are, a statement pronouncing the document's adoption by the states present, a formulaic dating of its adoption, along with the signatures of those endorsing it. Additionally, the convention's secretary, William Jackson, signed the document to authenticate the validity of the delegate signatures. He also made a few secretarial notes.
