On this date in 1787, 39 men who met in secret through the summer in Philadelphia signed the document that is the backbone of our government, the U.S. Constitution. Here is the preamble and the list of men who signed it:
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
