Answer:
Preamble.
Explanation:
The preamble was the term of the introduction. It explains the content ahead, and a little of the present history. It sets the stakes for the rest ahead.
"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, 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."
Hope this helps :)
