On September 17, 1787, the delegates of the Constitutional Convention met to sign the document they had created to replace the Articles of Confederation.  Of the 55 people who attended the Convention, only 39 signed on the document. Some left as the Convention progressed, whereas others refused to sign in protest.  Since Rhode Island refused to send a delegate, no representative from Rhode Island signed the document.  In addition to the 39 delegates, the convention’s secretary William Jackson also signed the document, not as a delegate, but in attestation of the document’s signing.

The Constitution was finally adopted by the Constitutional Convention in Philadelphia, and later ratified by special conventions in each of the then-existing thirteen American states.  Today, the United States Constitution is the supreme law of the United States of America.
