Unity

Petition from the citizens of Philadelphia praying for Congress to stand firm on the "Union, the Constitution, and the Enforcement of Law," February 5, 1861

We the People of the United States, in Order to form a more perfect Union... do ordain and establish this Constitution...

E pluribus unum—Out of many, one—expresses the ideal of our Union: many states, one nation. Representing all of the states, Congress has promoted national unity through a process of inquiry, debate, compromise, and consensus. These documents record the continuing legislative efforts to meet the broadest needs of the people.
