This comes from the Declaration of Independence. It really is a summary of the outcome of the Magna Carta, the document in which King John agreed (a bit unwillingly) to get the consent of the nobility before imposing questionable taxes needed because King John fought unnecessary wars in the opinion of the barons.

As it turned out, he moved the Magna Carta into the American Constitution.
